How to pack oil-resistant rubber sheet
The use of rubber products is common in our lives and work. So how much do you know about him, oil-resistant rubber sheets are one of so many types. Today, let's get to know them together. See what kind of special it is.
Packaging: woven bag, can be packed by weight or length. His oil resistance is low, he can't work in oil medium, the price is cheaper, he can only be used in some places with low oil resistance; for example, the laying of electronic products. It has medium oil resistance, can work in certain oils (such as engine oil, lubricants, vegetable oils), and has good sealing properties. It is mainly used for punching various oil-resistant oil seals, seals, rings and greases. Long-term laying of workbenches, grounds, and electronic products places that are in contact. Performance: The product has moderate hardness and high tensile strength and elongation. It can work in oil (oil, diesel, gasoline, lubricating oil) media, and has sealing and anti-swelling properties. Uses: It is used for punching various oil-resistant oil seals, seals, rings, laying on workbenches, floors, and electronic products in contact with grease. If the rubber products are in contact with the oil medium for a long time during use, the oil can penetrate into the rubber and cause it to swell, which will reduce the strength and other mechanical properties of the rubber. Oil can swell rubber because oil penetrates into the rubber, which causes molecular diffusion, which changes the network structure of the vulcanizate. The oil resistance of rubber depends on the polarity of the rubber and oil. Rubber molecules containing polar groups, such as cyano, ester, hydroxyl, and chlorine atoms, will cause the rubber to exhibit polarity. When the polar rubber is in contact with non-polar petroleum oils, the polarities of the two differ greatly, and the rubber is not easy to swell at this time.
