发明名称 POLYAMIDE HOSES FOR COMPRESSED AIR
摘要 The multi-layered flexible tube for compressed air has an internal layer in contact with the compressed air selected from polyamides, mixtures of polyamide and polyolefin with a polyamide matrix, copolymers with polyamide and polyether blocks, mixtures of polyamides and copolymers with polyamide and polyether blocks. The tube has an external layer of polyamide selected from PA11 and PA12, being the aliphatic polyamides resulting from the condensation of an aliphatic diamine which has 6 to 12 atoms of carbon and an aliphatic diacid which has 9 to 12 atoms of carbon and the copolyamides 11/12 which either have more than 90 per cent constituents 11 or more than 90 per cent constituents 12. The pipe has a reinforcement braid arranged between the external and internal layers.
