The O ring is mainly used for the static clearance and sealing of fluids (such as water, oil, air, chemical solvents, chemicals, etc.). The long-term service temperature is between -60 and 220 degrees centigrade. Due to different materials, the static pressure is less than 20MPa. Sometimes used for dynamic, dynamic use, less than 5MPa. Semiconductor Vacuum sealing.
Commonly used materials: thiakol rubber, silicone rubber, fluorine rubber, EPDM rubber, three acrylic, four C fluorine rubber, chloroprene rubber, epichlorohydrin rubber, fluorosilicone rubber, butyl rubber, hydrogenated butadiene acrylonitrile rubber, natural rubber, polyurethane rubber, styrene butadiene rubber, carboxylated nitrile rubber
