What Is The Difference Between PU Timing Belt And Rubber Timing Belt?

1. Different hardness: rubber synchronous belt is relatively soft (65 ShoreA), PU synchronous belt is slightly harder (90 ShoreA);
2. Different scope of application: rubber synchronous belt has a wider application range and lower manufacturing cost. Pu synchronous belt has certain limitations, but because it does not generate dust, it is widely used in food, medicine, beverage, electronics and other industries;
3. Different production process: rubber synchronous belt production process is relatively complicated; PU synchronous belt is directly extruded by extruder.
4. Different material properties: PU synchronous belt is more wear-resistant and chemically resistant than rubber synchronous belt.
