Abstract (en)

[origin: WO9907227A1] 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.
