The choice of seal material is of great significance to its sealing performance and service life. The performance of the material directly affects the performance of the seal ring.

According to the material, there are mainly the following types:

NBR sealing ring: suitable for use in petroleum-based hydraulic oil, glycol-based hydraulic oil, diester-based lubricating oil, gasoline, water, silicone grease, silicone oil and other media. The general temperature range is -40~120 ℃.

HNBR sealing ring: It has excellent corrosion resistance, tear resistance and compression deformation resistance, good ozone resistance, sunlight resistance and weather resistance. It has better abrasion resistance than NBR. The general temperature range is -40~150 ℃.

SIL sealing ring: It has excellent heat resistance, cold resistance, ozone resistance and atmospheric aging resistance. Has good insulation properties. The general use temperature range is -55~250 ℃.

EPDM sealing ring: It has good weather resistance, ozone resistance, water resistance and chemical resistance. The general temperature range is -55~150 ℃.

CR sealing ring: It is particularly resistant to sunlight and weather. The general temperature range is -55~120 ℃.

NR sealing ring: It has good wear resistance, elasticity, tear strength and elongation. The general temperature range is -20~100 ℃.

FKM sealing ring: It has the advantages of fluororubber and silicone rubber, and has good resistance to oil, solvent, fuel oil and high and low temperature. The general temperature range is -50~200 ℃.

Customers can choose the appropriate sealing ring according to the environment and temperature.
