Multilayer plastic pipe comprising an outer polyamide layer and a layer of a molding formed from a mixture of thermoplastic polyester and a compound having at least two isocyanate groups |
摘要 |
A plastic pipe having improved resistance to methanol-containing fuels and improved mechanical properties is provided. This is achieved by a multilayer plastic pipe consisting of at least one outer layer based on polyamide and at least one layer of a linear, crystalline polyester modified with isocyanates. With the aid of the invention it is possible to obtain plastic pipes having improved barrier properties against methanol-containing fuels and dimensional stability and mechanical load-bearing capacity.
