High performance thermoplastic vulcanizates (TPVs) for long term high temperature application

New thermoplastic vulcanizates (TPVs) based on Hydrogenated Styrene Block Copolymer (HSBC) have been developed for long term high temperature applications. A comparative study using these new TPVs and conventional TPVs (Polypropylene(PP)/EPDM rubber) was performed. Standard factorial designs were used to evaluate material performance. The material characteristics under investigation were rheological properties, dynamic mechanical properties, tensile properties and morphology. These new TPV compounds showed increased solvent resistance and elastic recovery of approximately 20%, respectively relative to conventional TPVs.
