PU timing belts generally use nylon wire (or steel wire, copper wire) as the tensile body, and are made of polyester, which has the characteristics of oil resistance, impact resistance, and beauty.

Rubber timing belt has good flexibility, good water resistance, PU is not water resistant, poor reciprocating workability, poor high and low temperature performance, good wear resistance. PU polyurethane timing belts are good under static conditions at room temperature. On the contrary, rubber timing belts are good. Polyurethane TPU timing belt is a kind of thermoplastic polyurethane material. It has high modulus, high strength, high elasticity, small permanent deformation, good bending performance, excellent wear resistance, oil resistance, low temperature resistance, aging resistance, and can reach Medical and health requirements. The wear resistance of polyurethane TPU timing belts is 8 times that of rubber timing belts, which is more hygienic than rubber timing belts, and is more suitable for food, medical industry, and clean production industries. At present, TPU timing belts have gradually replaced rubber timing belts. TPU timing belts are widely used in computer embroidery machines, beverage machinery, and colored glass manufacturing industries. The skeleton material used is aramid cord, not embroidered steel cord.
