The world’s leading cyclists started the Tour de France. To perform well, cyclists need power, stamina – and the right equipment. Racing bikes are lightweight and durable thanks to components made of high-performance materials, such as Tepex from LANXESS.

This year the Tour de France starts in Nice Moyen Pays, France. Three weeks later, on September 20, the grand finale will take place on the Champs-Élysées in Paris. Throughout the 3,500-kilometer-long race, cyclists perform at unbelievable levels and exert power on the pedals. That’s what enables the frontrunners, in around 20 to 40 minutes, to exert values of 5.8 to 6 watt per kilogram of bodyweight. Something last year’s victor Egal Bernal is capable of. At his weight, that’s the equivalent of 417 watts.

Ultra-light and highly durable

In addition to cyclists’ strength and stamina, performances like these are made possible by lightweight racing bikes. Regulations state they may not weigh less than 6.8 kilograms, equivalent to seven liter of water. Fulfilling these requirements often necessitates components such as brake levers or gearshift parts made of ultra-light yet highly durable materials.

One material that fits the bill is Tepex. The high-performance composite, made by LANXESS, is based on thermoplastic polymers reinforced with glass or carbon fibers. This accounts for its remarkable strength and stiffness, and makes it extremely lightweight. Especially the latter is decisive for Tour de France cyclists when battling uphill in the Alps and Pyrenees as it allows them to exert less effort to turn the wheel.

Usable for series production

“Generally speaking, in sports and bicycle manufacturing, fiber composites have been state of the art for around 30 years,” said Dr. Michael Münker, Global Tepex Manager in LANXESS’s High Performance Materials business unit. “Thermoplastic composites like Tepex® enable us to use them for series production. Actually, they are used in all bicycle

The days of disposable plastic products are numbered – alternatives are needed. The success of LastObject’s reusable cotton swabs shows that the market is ready for change. The company’s basic and beauty cotton swabs are both made of high-quality materials. To meet all requirements, the tip is made of THERMOLAST® M, a compound from KRAIBURG TPE that is often used for applications in the health sector.

Every day, 1.5 billion cotton swabs are produced worldwide, each to be used only once. And that’s where LastObject’s mission begins: the Danish company aims to promote the “zero waste” movement to make sure that the next generations will also have a clean and healthy world to grow up in. As the first step, this successful Kickstarter project is supplying reusable, hygienic and reliable alternatives to single-use items we use on a daily basis – with great success, they already sold more than 500,000 LastSwabs to happy customers all over the world. LastObject is thus responding successfully to EU Directive 2019/904, which bans single-use plastic products and will be coming into effect from mid-2021.
The basic requirements for their reusable cotton swab, LastSwab, are durability and quick and easy cleaning. Close attention was given to these qualities during the development process. According to the manufacturer, each individual product is designed for up to 1,000 uses. Another requirement was for the product to be skin safe and not cause any irritation when in repeated contact with the skin. It goes without saying that it meets this standard.
In Denmark, KRAIBURG TPE is collaborating closely with Teknisk Agentur, a trusted local distribution partner. The choice of material for the flexible, soft tip was a compound from the THERMOLAST® M series. This compound was also superior to its competitors in relation to processing options, adhesion and look and has the following properties:

• Hardness: approx. 40 Shore A
• Tensile strength: 8.0 MPA
• Elongation at break: 800%
• Tear resistance: 11.5 N/mm

The compound provides adhesion to polypropylene and polyethylene, high abrasion resistance, weldability and freedom from animal ingredients. It is processed using injection molding and extrusion. The rigid stick is made of polypropylene. The case is made of recycled ocean waste plastic (OWP) from the Danish company Zeaplast who collects plastic from the ocean and rivers in southeast Asia and recycles it. The entire product is molded by AMP, a well-known Danish injection molder.
And LastObject is doing more than just following a trend: The product effectively and measurably helps to save raw materials and waste, while reducing the carbon footprint. “It wasn’t only KRAIBURG TPE’s material that helped us implement the project. The entire process was very straightforward – all the way from identifying the product through to the service. KRAIBURG TPE, Teknisk Agentur, their Danish materials distributor, and the injection molder AMP are reliable partners who are helping us make the future more sustainable,” says Nicolas Aagaard, Co-founder at LastObject.

As part of its mission to tackle plastic pollution in the marine environment, The Ocean Cleanup project plans to sell goods made from the waste it recovers to fund its ongoing operations, and has just unveiled its very first product. Each pair of Ocean Cleanup sunglasses are made with plastics hauled in from the Great Pacific Garbage Patch, and are designed to be easily recycled themselves once they reach the end of their life.

After years of development and testing, the Ocean Cleanup Project finally set sail for the Great Pacific Garbage Patch towards the end of 2018, looking to use its giant floating booms to passively gather plastic waste in the area. Its first batch was hauled back to shore at the end of 2019, with the team then calling an end to a successful first mission.
The waste it collected throughout that mission has now been sorted, washed and compounded into certified high-quality plastic, which was used to build sunglass frames. These are paired with polarized lenses and stainless steel hinges, with the parts designed to be easily disassembled and recycled again at the end of their life. The glasses also come with a case made from recycled components of the first trash-catching system, and a pouch made from recycled PET bottles.
Using proceeds from the sales of these sunglasses, The Ocean Cleanup plans to fund its forthcoming missions to clean plastic waste from the marine environment. The group estimates that each pair sold will enable it to clean up an area spanning 24 football fields from the garbage patch, and if it sells every pair made from this first batch of recovered plastic, it will be able to clean 500,000 football fields worth of plastic.
That sure does sound impressive but somewhere between 5 and 12 million metric tons of plastic flow into the ocean each year, with that rate expected to triple in the next two decades, which equates to a whole lot of sunglasses. The Ocean Cleanup team will of course be very aware of this, but as a manifestation of its efforts so far and an example of a “circular” economy for plastics, its new eco-friendly eyewear isn’t a bad place to start.

A custom-formulated thermoplastic elastomer (TPE) from Teknor Apex Company has helped China’s ANTA Sports Products Limited to develop a running shoe that exhibits outstanding rebound resilience, enabling wearers to run for longer distances.

One of the world’s largest sportswear companies, ANTA collaborated with Teknor Apex to develop a high-dampening material for the midsole of a new line of running shoes. The midsole is a thick layer between the insole and outsole that is typically composed of a soft cushioning material. For its new running shoe, they collaborated to draw upon technology from outside the footwear industry to develop a midsole construction incorporating Monprene TPE. The companies carried out 40,000 running impact tests to identify the optimum solution that delivered the best rebound performance over extended periods of time.
The key property for this performance is rebound resilience, a measure of the energy returned to the runner in comparison with the energy applied for deformation of the midsole upon the impact with each of the runner’s strides. While standard midsoles on the market achieve 50% rebound, according to ANTA, this new midsole achieves a rebound of 70%. The reserved energy is transformed into running power, enabling the runner to go for longer distances.
“The collaboration between ANTA and Teknor Apex challenges conventional thought about running shoes by focusing on the resilience of the midsole, not just its cushioning property,” said Serene Cheng Sook Ee, Business Director for Teknor Apex’s Thermoplastic Elastomer Division. “The customized Monprene solution adds more spring back into each stride of the running shoe, and it also provides added comfort in ANTA leisure shoes.”
According to Teknor Apex, the customized Monprene is a 60 Shore A TPE that provides wrinkle-resistance, low compression set, tear resistance, and kink resistance. It exhibits excellent elasticity and remains flexible at low temperatures.
