MULTI-LAYER AUTOMOTIVE TUBE
摘要:
The disclosure introduces a multi-layer automotive tube, said layers comprising an inner layer made of thermoplastic polyurethane (TPU); a first intermediate layer made of ethylene vinyl alcohol (EVOH); a second intermediate layer made of polyamide and an outer layer made of polyamide. The inner layer made of TPU provides excellent chemical stability and is significantly less susceptible to degradation caused by frequent contact with fuels and/or fuel vapors. Said automotive tube can be produced using methods widely known in the prior art, such that industrial lines for producing said automotive tube can be adapted without great difficulty.
