TPU: TPU (热塑性聚氨酯)
Thermoplastic polyurethane, a flexible and tough polymer used for waterproof zipper film, coated tape and moulded pullers. TPU bonds well to polyester fabric, remains flexible at low temperature and resists abrasion and oils. Hardness, thickness and adhesion determine water resistance and hand feel. It can be clear or coloured and is processed by lamination, extrusion or injection. Bond strength and hydrostatic performance are verified before use.
