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.

Sirmax Receives a US Award and Invests Heavily

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.

Polyamide 12 elastomers stand out from competing thermoplastic moulding compounds thanks to a wide range of high-quality elastic properties. They are therefore used both for demanding precision injection-moulding parts and for select extrusion applications in the sports equipment and automotive sectors.

High-performance Elastomers: From Abrasion Resistant to Self-healing 

Regular offline control of the rubber compounds is an important part of present-day quality assurance concepts in the production of elastomer products. Since many of the tests involved in this are very time and cost intensive – and are also often inadequate for the intended purpose – an online quality assurance system has been developed in an effort to improve the process of evaluating the compound properties. 

Rubber Compounding: Online Quality Control 

In the production of rigid/flexible combinations, either thermoplastic elastomers (TPE), rubber, or liquid silicone (LSR) are used as the flexible component, depending on the case in question. As a specialist producer of multicomponent injection-moulded parts, Weigelt has a great deal of experience in processing all three materials. There are a number of challenges to be mastered when it comes to the application technology, however... 

Composite Parts: Flexibility in Rigid/Flexible Combinations 

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.
