Safety valve o-rings are widely used in petrochemical, energy and power industries. I tell you that for different media, you need to choose the right o-ring material. The following are the three most common types of safety valve O-ring materials:
1. The material of ethylene-propylene rubber o-ring has excellent water resistance, water vapor resistance, and heat resistance. It is suitable for use in safety valve sealing of high temperature water vapor working conditions (working environment and occasions) in the power industry.
芳香径化合物的有机溶剂。 Second, the perfluoroether rubber o-ring material is suitable for organic solvents containing wet hydrogen sulfide or aromatic compounds.
气密性、耐候性、抗老化性以及抗臭氧性和耐腐化性，适用于无机酸、燃油、纯氧、四氯化硅等介质，在安全阀密封中应用最为广泛了。 Third, the fluorine rubber o-ring material has excellent flame retardancy, air tightness, weather resistance, aging resistance, ozone resistance and corrosion resistance, suitable for inorganic acids, fuel oil, pure oxygen, silicon tetrachloride and other media , The most widely used in safety valve sealing.
