PLASTICS INDUSTRY EXHIBITIONS MAKE SUCCESSFUL RETURN TO ESSEN

The Plastics Recycling World Expo and Compounding World Expo and made a successful return to Messe Essen in Germany on 29-30 September 2021, attracting large numbers of exhibitors and visitors. This year’s event saw the addition of two new exhibitions, the Plastics Extrusion World Expo and Polymer Testing World Expo.

A total of 217 exhibitors took part in the event, which is 18% more than when the expos previously ran in 2018. This increase was despite the withdrawal of significant numbers of Chinese and other overseas exhibitors who were not able to participate because of travel restrictions.

The event attracted 3,269 visitors with 52% coming from outside Germany. It provided a welcome opportunity for the industry to get together after almost two years of lockdowns, travel bans and event cancellations. Many attendees were enjoying face-to-face meetings with customers and suppliers for the first time in 18 months or more. The five conference theatres at the event proved very popular, with attendees eager to catch up on the latest industry developments and market opportunties.

“This was the first major event that we could physically attend since the outbreak of Covid-19”, said Alexander Enthoven, head of business development at Kryha. “It was great to learn about new market and regulatory trends and to meet experts in the field”. Simon Bousquet, technical manager for polymer recycling at TotalEnergy, added: “The biggest players are here and it’s nice to be able to see everybody.”

Nikola Whyman, head of marketing at the event organiser AMI said: “Our total number of attendees was slightly lower than in 2018, which was expected given the ongoing restrictions on some overseas and company travel. However, we were very pleased to achieve 81% of our pre-pandemic visitor numbers. It underlines the value that these focused plastic industry shows deliver for exhibitors and visitors alike.”

The Plastics Recycling World Expo, Compounding World Expo, Plastics Extrusion World Expo and Polymer Testing World Expo will next take place in Cleveland, Ohio, USA on 3-4 November 2021, and they will return to Messe Essen in Germany on 14-15 June 2023.

Senbis Polymer Innovations B.V. releases whitepaper Evaluating recycled PET grades and making them Fit for Purpose.

Senbis’s whitepaper provides in-depth insights how recycled PET (rPET) can be evaluated and modified to convert the polymer into rPET based products that are ‘Fit for Purpose’.

During PET production, product use and PET recycling, the PET product quality can deteriorate significantly by:

Thermal degradation
Chemical and mechanical attack
The presence of contaminants

The whitepaper describes both the mechanical and chemical recycling technologies including its specific challenges. For most mechanical recycling processes, rPET still contains both solid and substance impurities which can affect the rPET quality. The whitepaper explains Senbis solutions to quantify the size distribution of solid particles in rPET by means of the unique Partisol test. The Senbis filtration test enable PET converters to assess the effectiveness to remove solid impurities in PET critical converting processes: the pressure increase of a bad quality rPET could be twice of a good quality rPET! In addition, Senbis can help to optimize the rPET purification and polymer quality by Solid State Polymerization (SSP).

Finally, yarn spinning is considered one of the most sensitive and critical processes to convert PET. Senbis can perform spinnability trials on rPET granulates to compare the virgin and rPET quality and spinning property performance on both pilot and semi-industrial scale.

Research cooperation between Kautex Textron and LANXESS

Substitution of steel and aluminium
Advantages in weight, functional integration and mass production
Technology demonstrator as the basis for series developments

Mumbai, December 17, 2021 – Speciality chemicals company LANXESS and Kautex Textron GmbH & Co. KG, a Textron Inc. company, have been collaborating for several years to research whether battery housings for electric vehicles can be designed and manufactured from technical thermoplastics. Together, they have developed a near-series technology demonstrator in a feasibility study. With a length and width of around 1,400 millimeters each, the system is a technically sophisticated, large-format all-plastic housing part with a weight in the mid-double-digit kilogram range.

The goal of the project was to demonstrate the advantages of thermoplastics over metals in terms of weight and cost reduction, functional integration and electrical insulation behavior.

“As a first step, we have completely dispensed with the use of metallic reinforcement structures while proving we can commercially produce these complex large components,” Felix Haas, Director Product Development at Kautex Textron, explains.

“Going forward, Kautex and LANXESS want to use the results of the cooperation to enter into development projects for series production with automotive manufacturers,” adds Dr. Christopher Hoefs, Project Manager e-Powertrain at LANXESS.

Single-stage manufacturing process with short cycle times

The demonstrator was developed based on the battery housing of a C-segment electric vehicle. It consists of a housing tray with crash structure, a housing cover and an underrun (underbody) protection. The housing components can be produced in a single-stage Direct Long Fiber Thermoplastic (D-LFT) molding process. LANXESS has optimized Durethan B24CMH2.0 as the material for the D-LFT molding compound. Kautex Textron compounds the PA6 for the process with glass fiber rovings. The local reinforcement of the housing structure is carried out using continuous fiber-reinforced thermoplastic composites of the Tepex dynalite brand from LANXESS. “The process enables shorter and thus more economical cycle times than the processes in which steel or aluminium are processed,” Haas explains.

No complex metal forming, fewer production steps

Today, housings for high-voltage batteries are primarily made of extruded steel or aluminium profiles. Depending on the vehicle class, the housing length and widths can be well over 2,000 or 1,500 millimeters, respectively. The size, the number of components and the numerous manufacturing and assembly steps make metal housings very cost-intensive. For example, complex structures made from strand press profiles require many secondary work steps such as welding, punching and riveting. In addition, the metallic components must be protected against corrosion in an additional process step by cathodic dip coating.

“Plastics, on the other hand, can fully exploit their design freedom. By integrating functions such as fasteners and thermal management components, the number of individual components of a battery housing can be greatly reduced. This simplifies assembly and logistical effort, which reduces production costs,” says Hoefs. Plastics are also corrosion-resistant and electrically insulating. The latter ensures, for example, that there is a reduced risk of the system short-circuiting. The low density of plastics and their potential for lightweight construction lead to significantly lighter housings, which benefits, among other things, the range of electric vehicles.

Complex mix of high requirements

High-voltage battery housings must meet a variety of highly demanding technical requirements. For example, they must be stiff and strong and yet be able to absorb a significant amount of energy in the event of a crash. This is tested via mechanical shock- and crush tests. The housings must also be flame-retardant in the event of a vehicle fire or thermal run-away of the electrical cells. Finally, the housings must be integrated into the vehicle structure.

“We continue to work together on optimizing the production and structural design of the components. The aim is to carry out the majority of the development work virtually, in order to save costs in prototype design and to shorten the time to market of future series components,” Hoefs says.

Solvay wins SPE Automotive Award for Slot Insulation Liner EV Innovation

PEEK magnet wire insulation and PPS coolant line honored for significant performance, production and sustainability benefits

Brussels, October 13, 2021 – Three e-mobility applications using Solvay specialty polymers are among the winners of The Society of Plastics Engineers (SPE) prestigious Automotive Awards in 2021. First place in the ‘New Mobility’ category of the Awards went to an injection molded rotor slot liner molded with Xydar® LCP, followed by a second place in the ‘Enabler’ category for a magnet wire insulation in KetaSpire® PEEK and a third place in the ‘Powertrain’ category for a coolant line using Ryton® PPS.

“We would like to congratulate our customers who developed and brought these applications to market, demonstrating the overall cost, performance and sustainability benefits that can be derived from our specialty polymers in demanding e-mobility systems and components”, says Georges Houtappel, Executive Vice President Transportation at Solvay. “After more than 20 years of enabling the design and manufacturing of high-performance and cost-efficient applications for internal combustion engines, the superior innovation potential of our materials for lightweighting, metal replacement and enhanced sustainability is now also extending to e-mobility applications such as e-motors, batteries and power electronics.”

The recognized applications in greater detail:

New Mobility Category Award, 1st Place – Slot liners injected, application developed and molded with Xydar® G930 30% glass fiber reinforced and flame retardant liquid crystal polymer (LCP) by Cobraplast, Italy, for one of Germany’s foremost automotive manufacturers. The part is used in the rotor design of an advanced-generation electric drive traction motor where it provides a barrier between the copper windings and the steel lamination of the rotor. In this small but critical application, Xydar® LCP replaces incumbent multi-layer films and provides significant cost and performance advantages. The material combines exceptional flowability to fill 0.65 mm thin sections over a length of 220 mm with zero warpage to meet tight tolerance specifications. In addition, it also ensures high stiffness to prevent breakage during assembly.

Enabler Category Award, 2nd Place – Magnet wire insulation developed by Essex Furukawa company, Germany, using solvent-free KetaSpire® polyetheretherketone (PEEK). Magnet wires coated with KetaSpire® PEEK are highly efficient in increasing power density and torque while reducing the weight and size of electric motors. The specialty polymer offers a thermal performance of 240°C and a dielectric strength of 197 kV/mm in combination with high ductility, stress crack resistance, long-term mechanical strength and outstanding chemical resistance.

Powertrain Category Award, 3rd Place – Cooling lines with coolant tubes extruded in Ryton® polyphenylene sulfide (PPS) XE 3500 (unfilled) and XE 5430 (30% glass-filled), complete with connectors injection molded in Ryton® R4-270 (40% glass-filled). Widely proven for cooling and venting lines in the high-heat environment of downsized internal combustion engines, Ryton® PPS also provides the chemical resistance, mechanical strength and flame retardancy needed for battery cooling lines in electric vehicles. In these applications, the polymer replaces lower performing polyamides as well as metals, which helps OEMs benefit from the lightweighting possibilities with plastics also in chemically and mechanically more demanding fluid handling systems.

E-mobility brings new technical challenges for carmakers in terms of component properties such as thermal conductivity, EMI shielding, CTI and dielectric strength. Solvay is constantly working with leading OEMs and Tiers to develop new specialty polymer grades offering enhanced performance for innovative e-motor, power electronics and battery applications, while helping manufacturers improve their cost balance and lower their carbon footprint.

The winners in the 20th SPE Central Europe Automotive Awards have underscored the vast potential of Solvay’s specialty polymers for optimizing the reliability, lifetime, cost efficiency and sustainability of e-mobility applications. Moreover, the company’s PEEK and PPS base polymers production in the United States is using 100% renewable energy.

LANXESS at the VDI “Plastics in Automotive Engineering” congress

Climate neutrality targeted by 2040
Material and technology solutions for charging infrastructure and driver assistance systems
Resource-conserving recycled materials
Lightweight solutions for vehicle batteries

Cologne, October 08, 2021 – LANXESS will be focusing its appearance at the 2021 VDI “Plastics in Automotive Engineering” (PIAE) congress in Mannheim on material and technology solutions for climate protection, the circular economy and lightweight design. The specialty chemicals company is aiming to become climate-neutral by 2040 and to reduce its greenhouse gas emissions, which currently amount to 2.5 million metric tons of CO₂, by 95 percent compared with the level at the company’s launch in 2004. The High Performance Materials (HPM) business unit is making a key contribution to that with its nitrous oxide reduction unit, which was recently brought on stream at the production site for polyamide 6 in Antwerp. “We will reduce annual emissions of CO₂ equivalents by a further 300,000 metric tons from 2023 onwards by investing in an additional plant to reduce nitrous oxide and optimizing our processes,” says Dr. Guenter Margraf, Head of Global Product Management at HPM.

New design for charging inlets

LANXESS sees a wealth of opportunities to use its Durethan-branded polyamides and polyesters from the Pocan product range not only in powertrains of electric vehicles, but also in charging infrastructure. Potential applications include components for charging plugs, sockets and stations as well as structural and cover elements in home charging stations, known as wallboxes. A wide range of dimensionally stable, flame-retardant, tracking-resistant and mechanically strong materials has been developed for components such as these. A modular charging inlet design concept developed by HPM shows what possibilities these compounds open up. “With a tailor-made material mix, we get the right material in the right place. At the same time, a high level of functional integration makes it easy to assemble the entire unit without any screws and using a minimal number of components, which keeps costs low,” says Margraf.

New design for radar sensors

Polyamides and polyesters are also good construction materials for assemblies that form part of driver assistance systems, such as radar sensors. For the latter, HPM has developed a design that allows heat to be dissipated by means of thermally conductive plastics in combination with metallic cooling elements. The sensor components are assembled using integrated snap fits and hot rivets, a process that is much less costly and time-consuming than using screws. Compared with previous methods of building radar sensors, the concept affords a greater degree of freedom in the selection of materials and facilitates the use of tailor-made compounds.

Polyamide with fibers from waste glass

The Durethan ECO polyamide 6 compounds with recycled fiber content of 30%, 35% and 60% by weight are another topic that will be receiving a lot of attention on the LANXESS stand at the PIAE congress. The recycled fibers are made from post-industrial waste glass. Ecocycle, an inspection company, has examined the recycled material content and the long-term use of the waste stream using the mass balance method and awarded an ecoloop certificate in accordance with ISO 14021:2016. The mass-balanced waste glass recycling is also certified according to ISCC-Plus (“International Sustainability and Carbon Certification”), a globally recognized system for sustainability certification. “We want to place more and more of our compounds on a sustainable footing in order to reduce our dependence on the consumption of finite resources and improve our carbon footprint,” explains Margraf. In Mannheim, HPM will present other new Durethan ECO variants as well as the first Pocan Eco product, which also contains recycled glass fibers.

Composite materials for lightweight electric vehicles

The expertise of LANXESS in lightweight design is illustrated by an E/E component carrier for the battery system of an electric vehicle, for example. The carrier boasts a high degree of dynamic strength and rigidity combined with a low weight thanks to the Tepex continuous-fiber-reinforced thermoplastic composites. “Production using the hybrid molding process in a cost-effective process results in a highly integrated structural component that reliably meets the exacting mechanical safety requirements applicable to the battery,” explains Thomas Malek, expert in lightweight design at HPM. The good flame retardant properties of Tepex are also advantageous in battery systems. Functionally integrated flat components in particular can be made from Tepex efficiently, yielding lightweight products that also exhibit high mechanical performance.

Hollow-profile hybrid technology to be launched on the market

The PIAE congress will also see HPM present innovations regarding hollow-profile hybrid technology that allows the functionalization of metallic hollow profiles with injection molding compounds. Advantageous properties of the resulting lightweight components include far greater torsional stiffness and strength than components produced using the “traditional” plastic-metal hybrid technology with sheet metal. “In optimizing our technology, we have made a great step forward. For example, the profiles no longer have to be supported against the high pressures of the molten plastic on the inside,” says Dr. Matthias Theunissen, expert in lightweight design at HPM. “The second phase of the market launch for our new lightweight technology has now begun. We are already working on several customer projects, which are at the prototype stage.”

The VDI Plastics in Automotive Engineering congress will take place on September 8 and 9, 2021, at the Congress Center Rosengarten in Mannheim, Germany.

500 th AD STAR block bottom sack conversion line worldwide from Starlinger goes to Côte d’Ivoire

The new conversion line is currently being installed at Plastica Sarl. in Abidjan and will
take up production in January 2022.

The ad*starKON SX + is the 500 th AD STAR sack conversion line Starlinger has sold worldwide. It converts woven polypropylene tape fabric into AD STAR block bottom valve sacks by means of heat sealing and has a production capacity of up to 120 block bottom sacks per minute. With this investment, packaging producer Plastica increases its AD*STAR sack production capacity by 45 million sacks per year to a total of 80 million sacks.

The company already operates a Starlinger block bottom sack conversion line since 2018 and supplies AD*STAR sacks to local and international cement producers such as CIMIVOIRE, Ivory Diamond Cement, Cimfaso and Cimasso. Plastica is planning to purchase a third Starlinger AD STAR conversion line in the near future.

“As we experience increasing demand for AD STAR cement sacks we have decided to expand production with another Starlinger block bottom sack conversion line”, says Abbas Badreddine, General Manager of Plastica. “Cement producers appreciate the excellent protection the bags provide for their product.”

AD STAR block bottom valve sacks have been developed and patented by Austrian woven packaging machinery manufacturer Starlinger & Co GmbH. The sacks are especially strong and tear-proof and provide excellent protection against humidity. Their brick shape makes AD STAR sacks perfect for stacking and allows for attractive sack design.

Due to the highly precise and fully automated bag conversion process the sacks are ideally suited for automated filling and palletising, and cement loss due to spilling and leaking are reduced to a minimum. The use of AD STAR sacks contributes to more sustainability in the cement industry as less cement enters the environment due to sack rupture, humidity, or leaking sacks and needs to be reproduced to compensate for
losses.

Currently, more than 17 billion AD STAR sacks per year are produced on Starlinger machines worldwide. Due to their special characteristics, they are a favored packaging for cement, but are also used for other dry bulk goods such as plastic resins, fertilizer or rice and flour.

Plastica Sarl. was founded in 1999 and produces woven PP bags for various applications as well as PE films and sacks and injection molded household and garden products. The company also operates a recycling facility for industrial and post-consumer plastic waste. Plastica caters to the cotton, agro-alimentary, and agro-industrial industry, wholesalers, and cement producers.
