teflon
It has outstanding chemical stability, thermal stability, anti-friction and self-lubricity, and its cracking temperature is more than 400. As a result, it is capable of operating at temperatures ranging from -200 to 300 degrees Celsius. In addition to free fluorine and alkali metals, it has excellent corrosion resistance to chemicals, solvents, hydroxides and acids [2].
Nitrile rubber compared with fluorine rubber material is to use a wide range of oil seal, the cost is low, but the heat resistance and sealing has improved significantly, but the cost is higher, and still have some adverse commonness of ordinary rubber materials, such as poor wear resistance and short service life, particularly sensitive response to the eccentric shaft, such as leakage phenomenon is relatively common. PTFE oil seal is a product with high technical content and will be the development direction of oil seal in the future [2].
