Thermoplastic Vulcanizates for Use at High Temperatures

Abstract

A thermoplastic vulcanizate is disclosed. The thermoplastic vulcanizate comprises a thermoplastic copolyester elastomer in an amount of about 5 wt. % or more to about 50 wt. % or less based on the weight of the thermoplastic vulcanizate, an at least partially cured elastomer in an amount of about 5 wt. % or more to about 90 wt. % or less based on the weight of the thermoplastic vulcanizate, and a compatibilizer in an amount of from 1 wt. % or more to about 20 wt. % or less. The weight ratio of the at least partially cured elastomer to the thermoplastic copolyester elastomer is less than 1.25. The thermoplastic vulcanizate exhibits an elongation at break of 200% or more.

Dependencies are inferred from the claim text.
