Oil seal of common materials are: acrylonitrile-butadiene rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene. Selection of seal materials, must consider the material of the working medium, compatibility of operating temperature range of the adaptability and the lip on the rotating shaft rotates at a high speed following capability. The general operation of the oil seal lip of the temperature is higher than the working medium temperature 20~50 ℃, in the selection of seal materials should be paid attention to. Please refer to the details: rubber types and characteristics. Oil seal oil seal use scope of work and materials: materials for butadiene acrylonitrile rubber ( NBR ) was -40~120, Alec rubber ( ACM ) -30~180 ℃, -25~300fluorine rubber ( FPM ).
