Use of polyurethane films as adhesive.

摘要

Thermoplastic polyurethane films with a Shore hardness of 75 A to 92 A and with an addition of 5 to 20 % by weight of polyether amide block copolymers and/or polyether ester block copolymers and their use for bonding to other substrates, in particular for foam-backing with polyurethane foam. The invention also relates to the use of an addition of 5 to 20 % by weight of polyether amide block copolymers and/or polyether ester block copolymers to thermoplastic polyurethanes with Shore hardnesses of 75 A to 92 A, based on the weight of the thermoplastic polyurethanes, to reduce the adhesion and/or blocking of monofilms made from thermoplastic polyurethanes by the blown film extrusion process.
