Natural rubber O-Rings is a latex from rubber trees known chemically as polyisoprene. Polyisoprene can also be copolymerized by monomer isoprene. Natural rubber has many excellent physical properties, including high elasticity, high strength and good wear resistance. Similar to SBR, due to the existence of double bonds in the polymeric backbone chain, it has poor tolerance to hydrocarbon oil, and is not suitable for UV resistance, oxygen, ozone. However, its weather resistance can be improved by additives.
Fluorine rubber seal ring (FKM/FPM) is made of ethylene fluoride and hexafluoropropylene copolymer elastomer. FKM (United States) and FPM (Europe) are both abbreviations of vinylidene fluoride fluoroprene, which vary only by region. Because of its excellent performance, fluorine rubber has been more and more widely used, well solve the problem of sealing under harsh conditions. With the continuous improvement of fluorine rubber manufacturing process and in-depth study of its application, this sealing material with the best comprehensive performance is bound to be popularized and applied in more fields in the future.
