High-performance thermoplastic elastomer

Sarlink ML-2355B from Teknor Apex Co. (Pawtucket, RI) is a new styrene block copolymer thermoplastic elastomer (TPE-S) for automotive interior parts such as cable ducts and grommets. The compound exhibits improved injection moldability compared with other elastomers while providing competitive physical properties and meeting stringent OEM requirements, the company claims. Sarlink ML-2355B compound has been approved for use in cable ducts by Volkswagen Audi Group (VAG). Used to guide cables in their route through spaces in pillars and other structures surrounding the passenger compartment, these ducts are complex parts with long flow paths and many undercuts, making them a challenge to mold and de-mold. Sarlink ML-2355B exhibits reduced viscosity for improved moldability, a wider processing window, and greater weld-line strength to facilitate air-assist de-molding.
