1) different materials: rubber synchronous belt using rubber, polyurethane synchronous belt using polyurethane;
2) hardness is different: rubber synchronous belt is relatively soft (Shore 65 degrees or so), polyurethane synchronous belt is slightly more hard (general synchronous belt in the Shore 92 degrees);
3) applications Different: rubber synchronous belt is relatively more widely used, manufacturing cost is also low. Polyurethane synchronous belt has certain limitations, but due to the characteristics of the dust will not be produced, is widely used in the food, medicine, beverage, electronics and other industries;
4) production process is different: rubber synchronous belt production process is relatively cumbersome, including refining, mixing, vulcanization and other processes, while the polyurethane synchronous belt will be a more concise process, the TPU type of synchronous belt on the extruder directly extruder, CPU type of synchronous belt to casting method, the CPU type of synchronous belt to casting method, the CPU type of synchronous belt to casting method, the CPU type of synchronous belt to casting method. TPU type synchronous belt directly extruder extrusion, CPU type synchronous belt to casting method can be completed;
5) material characteristics are different: polyurethane synchronous belt than the rubber synchronous belt is more wear-resistant, more resistant to acid and alkali and other chemical substances.
Simply put, each has its own characteristics, polyurethane synchronous belt so far has not been able to replace the rubber synchronous belt, you can look at the automotive synchronous belt, has been using the traditional rubber belt, the reason is that the rubber belt temperature can reach more than 140 degrees Celsius, and polyurethane synchronous belt is the highest working temperature of about 80 degrees.
