Sirmax Receives a US Award and Invests Heavily

At K 2022, it was clearly shown that with suitable materials not only can CO2 emissions be reduced, but also advantages in component design achieved.

The Japanese chemical company Asahi Kasei showed its concept vehicle at K 2022. The domed roof in particular could lead to a few changes in future automobiles.

With suitable materials CO2 emissions can be reduced and advantages in component design can be achieved.

The K 2022 offered an immense range of innovations and application examples for – and with more – sustainable materials. Interestingly hereby was that bio-based versions were extremely popular.

Shoes made from waste gas: genetically modified bacteria produce ethanol from waste gas, which is then used to create plastic, e.g. for the Cloudprime shoes from On.

The use of TPE materials with recycled content increases the sustainability of vehicles. They are also used more and more in the interior.

The selection of high-quality recyclate enables their use in demanding automotive applications.

The simple replacement of petroleum-based components with renewable alternatives in a well-established reactive extrusion process is a promising route to more environmentally friendly thermoplastic polyurethane elastomers (TPU). However, this requires a comprehensive understanding of the interactions between chemical reactions and material flow within an extruder, as well as a thorough understanding of the effects of heat and shear on polymerization and melt processing.

Increasing demands on component functionality and the need for efficient manufacturing processes are keeping multi-component injection molding squarely in the focus of plastics processing. Not all materials can be processed reliably in the desired combination. The new InMould-Plasma process, which is fully integrated into the injection molding process, facilitates more-efficient production and paves the way for completely new material combinations.

Kraiburg TPE’s latest thermoplastic elastomer (TPE) has been specially developed for consumer and industry applications and contains up to 40 % post-consumer recyclate (PCR). In accordance with standard ISO 14021, the manufacturer recycles materials that end consumers from households and the industry can no longer use for their intended purpose.

The latest solution from Kraiburg TPE makes a post-consumer recycling proportion of 40 % possible. The TPE is partly made from household waste.

Plastic manufacturer Dow has announced the launch of more sustainable polyolefin elastomers. The new brand will help the footwear industry to unlock a lower carbon footprint and develop more sustainable products.

Plastic manufacturer Dow has announced the launch of more sustainable polyolefin elastomers. The new brand, called Engage Ren, will help the footwear industry to unlock a lower carbon footprint and develop more sustainable products which offer the same high-performance results.

 According to Dow, the key benefits that the new polyolefin elastomers will offer manufacturers in the footwear industry are improved foam quality and polymer consistency, a better resilience, lighter foams with equivalent hardness and improved abrasion resistance and durability.

Engage Ren polyolefin elastomers are produced using renewable energy and plant-based feedstocks such as used cooking oil. As only waste residues or by-products from an alternative production process are utilized, these raw feedstock materials do not consume extra land resources nor compete with the food chain. The plant-based polymers deliver equivalent performance in the final application as fossil-fuel counterparts and therefore do not require reformulation.

“Manufacturers, brands, retailers and consumers all recognize the role they play in reducing the impact of climate change and as a result, are seeking out more sustainable options,” said Imran Munshi, Global Bio-Polymers and Consumer Market Manager at Dow.

Crocs is the first footwear brand to go-to-market with this new material technology. Dow has begun supplying plant-based polymers for use in Crocs’ manufacturing process of its proprietary Croslite material, which have an even lower CO2 impact than their current material. The company will take a mass balance approach to scaling the percentage of plant-based polymers into its footwear over time.
