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.

Is Bio the New Standard?

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.

Recycling Content for Automotive Interiors

Kraiburg TPE is expanding its portfolio of thermoplastic elastomers (TPE) for automotive interiors with grades with a recycling content of up to 38 %.

Kraiburg TPE is expanding its portfolio of thermoplastic elastomers (TPE) for automotive interiors with grades with a recycling content of up to 38%.

The post-industrial recycled raw material used is waste material derived from other companies’ manufacturing process for plastic products. Possible applications of the TPEs include anti-slip mats, floor mats, soft components in cup holders, as well as fixation elements. The series is also suitable for other applications requiring a hardness range between 60 and 90 Shore A.

Good Abrasion Resistance and Excellent Flowability

Strict OEM requirements for emission and odor are fulfilled and the material can be either combined with polypropylene in co-injection molding applications or used as single soft component solution. In addition, Interior PIR TPE provides good abrasion resistance and excellent flowability combined with low density to keep the part weight at a minimum. “We’re expanding our product range to include Interior PIR TPE in response to the sustainability issues raised by OEMs. We’re sure our customers will benefit substantially from the option of using TPEs based on recycled raw materials for automotive interiors,” says Matthias Michl, Head of Automotive Application Development at Kraiburg TPE.

The company is now able to provide the product carbon footprint (PCF) of compounds for many products. The PCF quantifies the CO2e-footprint – in this case within the system boundaries cradle-to-gate. The global warming potential (GWP) of a product is calculated, indicating how much the product contributes to global warming from raw material extraction to the product manufacture’s gate. Producers require this value to assess the carbon footprint of their components, and ultimately of the whole vehicle. As stated in a press release, Kraiburg TPE claims full transparency in assessing the PCF and calculates the values according to DIN EN ISO 14067 and DIN EN ISO 14044, following the GHG Protocol.
