Polyurethane PU timing belt is made of imported thermoplastic polyurethane material, which has high abrasion resistance. Various types of steel wire cores ensure that it still maintains good movement ability in transmission and has small production tolerances. During the production process, a layer of nylon is applied to the tooth surface and/or the back of the tooth to ensure that the operation characteristics in special applications remain unchanged, and a layer of polyurethane can be thickened on the back of the belt to prevent corrosion or high loads.   1. Anti-aging, waterproof, anti-ultraviolet UVA, anti-ozone; 2. Working temperature -30℃+80℃ can withstand up to +110℃ in a short time; 3. Highly oil and grease proof; 4. Resistant to most acid and alkali corrosion.
