MULTI-LAYER PLASTIC PIPE

摘要

MULTI-LAYER PLASTIC PIPE A multi-layer plastic pipe consisting of at least one outer layer based on a polyamide and at least one layer made of a moulding composition based on a mixture of 99 to 60 % by weight of a partially crystalline thermoplastic polyester and 1 to 40 % by weight of a compound having at least two isocyanate groups, which are present in the moulding composition in a concentration between 0.03 and 3 % by weight. The pipes have a good barrier effect against the transported medium, particularly with methanol-containing fuels, as well as a satisfactory dimensional stability and mechanical load-bearing capacity.
