PU polyurethane rubber seal ring

The mechanical properties of the polyurethane rubber are very good, wear resistant, and high pressure resistance is far better than other rubber. Non-aging, ozone resistance, and oil resistance, but high temperature is easy to hydrolyze. It is generally used for high pressure resistance, wear-resistant sealing links, such as hydraulic cylinders. The temperature range is usually used as -45 ~ 90 ° C.

FFKM full fluorine rubber

Very excellent chemical resistance, acid, alkali, ketone, ester, ether, strong oxidant, etc. are most chemical. The highest heat resistance can be 320 ° C. Usually used for sexually solving sealing problems, the price is nearly 100 times the general rubber material, very expensive.
