Thermoplastic elastomer composition and process of production thereof and hose using thermoplastic elastomer composition and process of production thereof

摘要

A thermoplastic elastomer composition which, when used for the inner tube and/or outer cover of a hose, can improve the hose flexibility at an ordinary temperature and low temperature, oil resistance, and cold resistance and can reduce the production costs since it does not require a vulcanization step and a hose having said properties using this elastomer composition for its inner tube and/or outer cover and a process and apparatus for the production thereof.
