Thermoplastic elastomer composition with an improved rubber pelletization process

摘要

A kind of wearing quality, thermotolerance and flexible composition for thermoplastic elastomer with raising, comprise (A) halogenated isobutylene elastomer, (B) polymeric amide and (C) melt temperature greater than 70 ℃ with less than the dynamic vulcanization mixture of 200 ℃ antioxidant, wherein elastomerics (A) is dispersed in the external phase of polymeric amide (B) with microcell, and component (A) and dynamic vulcanization mixture (B) at antioxidant (C) as dynamic vulcanization in the presence of the anti-hard caking agent.
