what materials is the pu film material made of?

TPUit is the abbreviation of thermoplastic urethane, and its chinese name isthermoplastic polyurethane elastomer。

tpu is a polymer material formed through the reaction and polymerization of diisocyanate molecules such as diphenylmethane diisocyanate (mdi) or toluene diisocyanate (tdi), macromolecular polyols and low-molecular polyols (chain extenders). its molecular structure is the rigidity obtained by reacting diphenylmethane diisocyanate (mdi) or toluene diisocyanate (tdi) and a chain extender with a diisocyanate such as diphenylmethane diisocyanate (mdi) or toluene diisocyanate (tdi) block. molecules are formed by alternating reactions with macropolyols.tpu filmit has excellent high strength, toughness and anti-aging properties and is a mature environmentally friendly material.

at present,tpu film manufacturersoftpu filmit has been widely used in fields such as medical care, electronic appliances, industry and sports. it has high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, weather resistance, etc. unmatched by other plastic materials. at the same time, it has many excellent functions, such as high waterproof and moisture permeability, windproof, coldproof, antibacterial, mildewproof, warm, uv resistant and energy release.

thermoplastic polyurethane elastomer tpu can be divided into polyester type and polyether type according to its molecular structure. according to the processing method, it can be divided into injection molding grade, extrusion grade, blow molding grade, etc.
