MULTI-LAYER TUBE

摘要

A multi-layer tube (1) which comprises a tube base material (3) comprising a fluororubber type thermoplastic elastomer composed of a rubber phase and a crystalline phase and having a hardness of HDA 40 to 70 as measured according to JIS K 7215 and a coating layer (2) laminated on the inner surface of the tube base material (3), wherein the coating layer (2) is a blend of the above fluororubber type thermoplastic elastomer with a vinylidene fluoride-hexafluoropropylene-tetrafluoroethylene ternary copolymer and has a hardness of HDA 70 or more and HDD 80 or less as measured according to JIS K 7215.
