Oil seals commonly used materials are: NBR, fluorine rubber, silicone rubber, acrylate rubber, polyurethane, PTFE and so on. When selecting oil seal materials, it is necessary to consider the compatibility of the material to the working medium, the adaptability of the working temperature range and the following ability of the lip flange to rotate the rotating shaft at high speed. General oil seal work when its lip edge temperature is higher than the working medium temperature 20~50℃, in selecting oil seal material should pay attention to. For details, please refer to the types and characteristics of rubber. The working range of oil seals is related to the materials used in oil seals: the material is NBR (NBR)-40~120℃, Alex Rubber (ACM)-30~180℃, fluorine rubber (FPM)-25~300℃.
