What is TPU ? What is its applications ?


The tpu material is the abbreviation of Thermoplastic Urethane, and the Chinese name is thermoplastic polyurethane elastomer. TPU is a polymer material formed by the reaction and polymerization of diisocyanate molecules such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) with macromolecular polyols and low-molecular polyols (chain extenders).


Its molecular structure is a rigid block obtained by the reaction of diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) and a chain extender, and diisocyanates such as diphenylmethane diisocyanate (MDI) or toluene diisocyanate (TDI) The flexible chain segments obtained by the reaction of molecules and macromolecular polyols are alternately formed.

TPU development prospects

TPU is mainly used in inflatables, health care/medical products, vacuum forming, tapes, foaming of cushions, tapes, protective layers, cushions, etc.

At present, the main domestic production is low-end TPU, so the development potential of China's domestic mid-to-high-end market is huge. TPU has huge application prospects in many fields. TPU is mainly used in melt-spun spandex, shoe material industry, synthetic leather, film industry, hose and cable industry, caster industry, adhesive industry, etc. But at the same time in many fields, they are also facing the problem of strong substitutes competition. Only domestic TPU manufacturers continue to innovate and invest, increase in-depth TPU research and development, and reduce production costs, in order to achieve sustainable development and promote TPU products. Apply to more fields.

TPU film is mainly used in the lamination of high-end fabrics, and can be used in clothing, footwear, thermal underwear and agricultural cold-proof film. TPU film can also be used for welding hollow products, fabric laminates, protective coatings, foam sealing, wear-resistant coatings, etc.

TPU films and sheets can be extruded by an extruder, the thickness is from a few microns to a few millimeters, and pigments can be added to make products of various colors. TPU film has good abrasion resistance, puncture resistance, tear resistance, elasticity, adhesion, and weldability, so it can be used to prepare conveyor belts, and can be used to convey dry, wet, and Fatty foods.
