Composite material, useful for laminating porous substrates e.g. synthetic foam materials, comprises a low softening layer made from thermoplastic copolyester elastomer and a high softening layer made of thermoplastic polyurethane

摘要

Composite material comprises a lower and a higher softening side. The composite consists of at least one high softening layer made from thermoplastic copolyester elastomer and low softening (20[deg] C) hot-melt material made from the thermoplastic polyurethane that is tacky when hot. The composite is produced by film-coextrusion method. An independent claim is included for a process for laminating or sealing porous substrates, preferably synthetic foam materials, textile materials, seams, non-woven fabrics, leather and/or cracked leather with the laminating films, comprising heating the low softening side of the film above its softening range and adhering the multilayer film with the substrate. The softened side having the low softening range is facing the substrate.
