PU polyurethane rubber seal ring

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.
