A HOSE FILM ON THE BASIS OF POLYAMIDES

摘要

The invention concerns hose films on the basis of polyamides which can be used for production of hose films orientated in two axes usable in manufacture of paste-like and viscous products which may be subjected to heat treatment in temperature range 70-125 DEG C. A hose film on the basis of polyamides, including polyamide 6, aliphatic copolyamide, aromatic polyamide, containing hexamethylenediamine and teraphthalic acid units and a copolymer, including olefin units, is claimed which additionally contains a ionomer resin. As aliphatic copolyamide, it contains a copolymer of polycaprolactam, polyhexamethylenediamine and adipic acid. As copolymer including olefin units, it contains a mixture of graft copolymers on the basis of derivatives of carboxylic and polycarboxylic acids. The components are present in following amounts (weight parts): Polyamide 6: 77-83; copolymer of polycaprolactam and of polyhexamethylenediamine and of adipic acid: 7-13; aromatic polyamide, containing hexamethylenediamine and terephthalic acid units: 3-7; ionomer resin: 3-6; mixture of graft copolymers on the basis of derivatives of carboxylic and polycarboxylic acids: 0.1-5.
