The rubber mold oil resistant rubber sheet is mainly made of nitrile rubber plus reinforcing agent and filler. The degree of oil resistance of the oil-resistant rubber sheet is determined by the quality of the nitrile rubber and the content of nitrile in the rubber sheet. The higher the quality of the nitrile rubber and the higher the content of the nitrile rubber, the higher the oil resistance of the oil-resistant rubber sheet.
Industrial rubber sheet national standards will be rubber mold oil rubber sheet is divided into three categories: A type oil, B type oil, C type oil three. Class A oil-resistant rubber sheets have low oil resistance and cannot work in oil media. The price is relatively low. They can only be used in places where the oil resistance is relatively low. They are mainly used in workbenches, floors, electronic product places that come into contact with oils and fats. Laying. Class B oil-resistant rubber sheet is medium in oil resistance, and can work in certain oils (oil, lubricant, vegetable oil) media, with good sealing properties; rubber mold is mainly used for punching various oil-resistant oil seals, seals, Circles, benches, floors, and electrical products that come into contact with oils and greases are used for long periods of time.
Type C oil-resistant rubber sheet is a high-purity nitrile rubber sheet. Its oil resistance is the best among synthetic rubber sheets, and rubber molds are more expensive. It can be used in long-term working under high temperature (oil, diesel, gasoline, lubricating oil). It has sealing and anti-expansion properties. It is mainly used for punching various high-performance oil-resistant oil seals, seals and rings. It can be used as an oil tank. , oil pipeline seal use.
