Essentially rubber: Sustainable shock absorber

Leading-edge designs and applications showing how elastomer materials contribute to all aspects of life and lifestyle in the 21st century:

Trelleborg AB and Celanese have developed a ‘sustainable’ jounce bumper for the automotive industry: using a blow-moulded Hytrel thermoplastic elastomer instead of commonly used crosslinked polyurethane foam. The suspension unit is said to integrate up to four parts into one, making it both durable and recyclable. It does not require a separate base cup or ring and has integrated dust protection. Snap-fit assembly further enhances durability and eliminates contact with the strut, thereby reducing friction, abrasion and noise. The product can be used in temperatures ranging from -40°C to +140°C.
