Requirements For Sealing Materials Of Fluorine Rubber O-ring

Types and uses of materials commonly used for manufacturing fluorine rubber O-ring: O-ring materials should meet the requirements for sealing functions. Due to the different media being sealed and the different working conditions of the equipment, different adaptability of sealing materials is required. The requirements for sealing materials are generally:
1) The material has good compactness and is not easy to leak media;
2) Have appropriate mechanical strength and hardness;
3) Good compressibility and resilience, small permanent deformation;
4) Does not soften or decompose at high temperatures, does not harden or crack at low temperatures;
5) Good corrosion resistance, able to work in acid, alkali, oil and other media for a long time, with small volume and hardness changes, and does not adhere to the metal surface;
6) Low friction coefficient, good wear resistance;
7) It has the flexibility of combining with the sealing surface;
8) Good aging resistance and durability;
9) Convenient processing and manufacturing, cheap price, easy to obtain materials.
Fluorine rubber O-ring is a commonly used sealing material. In addition to rubber, suitable sealing materials include graphite, polytetrafluoroethylene, and various sealants.
