What are the materials of the gasket?
Rubber gasket materials are usually NBR (nitrile rubber), SBR (styrene-butadiene rubber), HNBR (hydrogenated nitrile rubber), EPDM (ethylene propylene diene rubber), SILICONE (silicone), VITON (fluoroplastic), CR (chlorine Dingjiao), FFKM (Perfluoroelastomer), etc.
The use of NBR nitrile rubber as the material for rubber gaskets is the most common and the most cost-effective. The use of FFKM perfluororubber gaskets is generally more sophisticated, such as in the field of space rockets. Because its price is quite expensive, it has excellent performance and can exceed many metal materials.
