MULTILAYER PLASTIC PIPE, TRANSPORT CONDUIT PIPE AND HOLLOW MOLDED BODY CONSISTING OF SAID PLASTIC PIPE AND PRODUCTION OF SUPPLY PIPE PIECE AND TANK CONTAINER

摘要

PURPOSE: To provide a polyamide pipe having a favorable shut-off actin to methanol-containing fuels, a sufficient dimensional stability, and a sufficient mechanical load capability. CONSTITUTION: This multilayer plastic pipe comprises I, an external layer, II, an intermediate layer being adjacent to an internal layer and comprising a molding material of which the base is a mixture comprising following components: (a) polyamide and (b) polyglutarimide, and III, the internal layer comprising a molding material of which the base is polyvinylidene fluoride. Then, respective adjacent layers are combined with each other in a friction contact manner.
