As we all know, rubber synchronous belt is a very widely used industrial belt, but in the transmission requirements of high precision of some special occasions, but need to use 3M polyurethane synchronous belt! Such as: toasters, etc.
Yonghang Transmission Belt summarizes 4 differences between 3M polyurethane synchronous belt and rubber synchronous belt:
1.3M polyurethane synchronous belt is more environmentally friendly compared to rubber synchronous belt, because the polyurethane synchronous belt is not easy to fall off the powder, with the pulley contact process will not be dust sticking on the top of the pulley
2.relative to the rubber synchronous belt. Compared with the rubber synchronous belt, polyurethane synchronous belt stretch less, while the rubber synchronous belt in the running process is slowly stretched, for the accuracy of more or less will be a little bit affected, so the maintenance personnel need to be adjusted in about half a year on the rubber synchronous belt.
3. Polyurethane synchronous belt made of thermoplastic polyurethane material, with high wear resistance, wear resistance, permanent variability, small, aging resistance, can meet the health and medical requirements, more than rubber synchronous belt is suitable for use in the food, medical industry, widely used in clean room workshops and precision transmission devices!
4. rubber synchronous belt hydrolysis resistance, heat resistance, impact resistance is better than polyurethane synchronous belt, polyurethane synchronous belt is not water resistant, many times flexing internal heat generation, high and low temperature resistance performance is poor. At room temperature under static conditions polyurethane synchronous belt is good. On the contrary, rubber synchronous belt is good.
