Recycling Content for Automotive Interiors

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.

With the increasing digitalization of injection molding, new process parameters are coming under the spotlight. Engel, together with the Polymer Competence Center Leoben and Montan University Leoben, Austria, is using machine-learning methods to explore the potential of mold breathing for quality assurance in rubber injection molding. This research project was supported by the partner company SKF Sealing Solutions Austria.

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.

LSR optics offers a wide range of applications due to the optical brilliance, the possibility to produce undercut shapes not to mention the competitive pricing. The adhesive surface which is almost impossible to clean however makes the LSR parts vulnerable against contaminations. This characteristic however limits the possible application fields. To overcome this limitation Wilhelm Weber has partnered with Fraunhofer IFAM in a recent research project.

Half of the board was treated with VUV while the other half has covered. Afterwards norm dust was applied onto the board uniformly and than knocked off (once) in upright position. The dust sticks to the untreated areas while falls of the treated areas

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.

Not only on Earth do elastomers make an important contribution to everyday life in demanding applications but they are also in demand for satellites or probes. Alongside typical worldly properties such as temperature and chemical resistance, materials deployed in space are subject to other conditions specific to this environment, such as enormous centrifugal and gravitational forces. These place special demands on the polymers we are familiar with.
