There are many materials that can be used to produce NBR rubber o-rings from China. According to the oil resistance, the materials can be divided into polar rubber and non-polar rubber. Among them, polar rubber belongs to oil-resistant rubber, and non-polar rubber belongs to non-oil-resistant rubber. You know the difference What is the oil resistance of the material seal?

　　1. NBR rubber o-rings from China Fuel resistance:

　　Among many materials, FMVQ fluorosilicone rubber and FKM fluororubber have excellent resistance to fuel oil. Among them, chloroprene rubber and chlorinated polyethylene rubber have poor fuel resistance, while the fuel resistance of NBR nitrile rubber is not fixed. Yes, the fuel resistance will change with the content of acrylonitrile.

　　2. NBR rubber o-rings from China Mixed fuel resistance:

　　In terms of resistance to mixed fuel oil, FMVQ fluorosilicone rubber and FKM fluororubber have very good resistance to mixed fuel oil, while acrylate rubber has poor resistance to mixed fuel oil. Because the acrylonitrile content in the material increases, the fluorine rubber with high fluorine content can be more stable in mixed fuel resistance.

　　3. NBR rubber o-rings from China Mineral oil resistance:

　　NBR has good mineral oil resistance, and its resistance to mineral oil will increase due to the increase of acrylonitrile content.

　　4. NBR rubber o-rings from China Acid and oxidative fuel resistance:

　　For acid oxidized fuel, the hydroperoxide in acid oxidized fuel can reduce the performance of vulcanizate, so vulcanizate is generally not used in the fuel system.

　　We know that there are many materials of NBR rubber o-rings from China, and different materials have different properties and characteristics.
