TPU Film is manufactured using thermoplastic polyurethane resin, which is generally produced from combinations of polyols, diisocyanates, and chain extenders. Different chemical formulations create different TPU families, including polyester-based TPU and polyether-based TPU. The selection depends on the required flexibility, hydrolysis resistance, abrasion performance, chemical resistance, temperature performance, and other application-specific characteristics. TPU Film is commonly produced using extrusion-based manufacturing processes, where the TPU material is melted and formed into a continuous film. Depending on the required specifications, manufacturers may use cast film extrusion, blown film processes, calendaring, or specialized extrusion and coating technologies. Advanced processing allows manufacturers to control film thickness, surface finish, transparency, hardness, and mechanical properties. TPU Film is naturally flexible and elastic because of the molecular structure of thermoplastic polyurethane. It can withstand repeated bending and stretching while maintaining useful mechanical performance. It also offers excellent abrasion resistance, making it suitable for applications exposed to friction and regular handling.
