Timing belt material: the difference between rubber and polyurethane

1. Concepts and characteristics of rubber and polyurethane

 

Rubber is a polymer compound with elasticity and wear resistance and is widely used in timing belts. Polyurethane is also a polymer compound with characteristics such as wear resistance and smooth vibration. It is also used in the production of timing belts like rubber.

 

2. Advantages and Disadvantages of Rubber and Polyurethane

 

Advantages and disadvantages of rubber:

The advantages of rubber timing belt mainly include good elasticity, strong vibration absorption capacity, low noise, and economical and practical. But at the same time, rubber timing belt also have related shortcomings, such as low temperature range, poor heat resistance and oil resistance.

 

Advantages and disadvantages of polyurethane:

In contrast, the advantages of pu timing belt include high temperature, oil resistance, wear resistance, etc. In addition, pu timing belt also have the characteristics of light weight and long life. But at the same time, the price of pu timing belt is slightly higher than that of rubber timing belt.

 

3. Differences in application scenarios

Since rubber and polyurethane timing belt have different characteristics, their application scenarios are also different. Rubber timing belts are mainly used in low-speed, small-load industrial applications, such as textile machinery, food machinery, home appliances, etc.; while polyurethane timing belts are mainly used in high-speed, large-load industrial applications, such as digitally controlled machine tools, automated production lines, etc.
