In the mid-19th century, the first O-ring appeared. To this day, only over a hundred years have passed, but the O-ring has developed comprehensively and is widely used in sealing various vacuum systems due to its simple structure, convenient loading and unloading, reliable sealing, low dynamic friction resistance, and no need for periodic adjustment.

There are two types of rubber commonly used in vacuum systems: vulcanized rubber made from natural latex, synthetic rubber (including butyl, chloro, and nitrile rubber), and silicone rubber, fluororubber, etc.

To solve the problem of vacuum rubber sealing, in addition to having the correct sealing structure design, the reasonable selection of sealing materials is also crucial. The main factors affecting vacuum sealing include the heat resistance, compression deformation resistance, air leakage rate, air permeability, air release rate, and sublimation (weight loss) of rubber.

Through different experiments, it has been found that fluorine adhesive, as a sealing material for vacuum, is very excellent. Jiacheng New Material (SJK) can provide high vacuum fluoroelastomer O ring with different type of FKM, 26 type, 246 type, FEPM, FFKM and etc. based on your requirements for vacuum degree.
