Polyether-type thermoplastic polyurethane elastomers are generally synthesized from polytetramethylene ether glycol (PTMGE), MDI and a small-molecule chain extender. Compared with polyester thermoplastic polyurethane elastomers, polyether thermoplastic polyurethane elastomers have excellent low-temperature performance, hydrolysis resistance and elasticity, are widely applied to the aspects of films, wires and cables, spandex fibers and the like, and are researched more and more deeply.
The hot melt adhesive film is a film product with or without release paper, and can be conveniently operated continuously or intermittently. Can be widely used for bonding various fabrics, soles, nylon cloth, water-proof materials, leather, polyester fibers, high polymer materials and metals.
