摘要: A thermoplastic elastomer composition which comprises 25-95% by weight of a polyamide and 75-5% by weight of a halogenated butyl rubber, a chlorosulfonated polyethylene or both thereof. Said composition is excellent in resistance to Freon gas permeation and has good oil resistance and low-temperature resistance. A hose wherein the layer to be contacted with a gas is made of the above thermoplastic elastomer composition is suitable as a Freon gas R-22 hose.
