The use conditions of rubber sheets are very relaxed, and they can be used for a long time both indoors and outdoors. Rubber sheets can produce many special properties and applications, which are important factors for the development of the rubber sheet industry (such as highly insulated rubber sheets, anti-static rubber sheets, high-temperature rubber flooring, oil resistance, acid and alkali resistance, etc.). So, today we will introduce the characteristics of oil resistant rubber plate inspection and distinguish it from ordinary rubber to help you better understand. Rubber products come into long-term contact with oil media during use, and oil can penetrate into the interior of the rubber, causing expansion, thereby reducing the strength and other mechanical properties of the rubber. Oil can dissolve rubber because after oil penetrates the rubber, molecules diffuse and the network structure of vulcanized rubber changes. According to the oil resistance of rubber and the polarity of rubber and oil, rubber molecules contain polar groups (such as bromine, ester, bromine, chlorine atoms, etc.), and rubber can display polarity. When rubber with high polarity comes into contact with non polar petroleum oils, the polarity difference between the two is significant, and rubber is not prone to expansion. It has good oil resistance to non-polar oils such as Nitrile rubber, hydrogenated Nitrile rubber, acrylic rubber, chlorohydrin rubber, chlorosulfonated polyethylene rubber, fluororubber, fluorosilicone, etc.
