Details

Arnitel® is a thermoplastic co-polyester with a very high temperature resistance. Arnitel® ECO TPC is a biobased alternative.

Benefits

• Arnitel® TPC allows for cost effective solutions since it yields thermoplastic processing advantages over rubber, resulting in faster cycle times in compraison with other TPE's
• Arnitel® TPC allows for reliable solutions due to its high abrasion resistance, excellent load bearing capacity, great fatigue, and environmental resistance and due to a very consistent performance over temperature ranges from -55°C (-67°F) to +150°C (+300°F) and longest lifetime to failure as compared to any other rubber or class of TPE's used in this application
