Project details

Silicone rubber O-ring is a circular product made of silicone rubber, which belongs to a category of silicone rubber products. The general silicone rubber O-ring is mainly composed of VMQ methyl vinyl silicone rubber. It has excellent high-temperature resistance, chemical corrosion resistance, and compression resistance, as well as high transparency and anti mold properties.

When installing an O-ring, in order to prevent it from moving in the sealing groove, it is generally placed in a certain degree of tension. However, if this installation method is used for rotational motion, it will produce adverse results. Because the O-ring seal that has already been tightly clamped on the rotating shaft contracts due to the frictional heat generated by the rotational motion, which increases the clamping force. Such repeated cycles greatly promote the aging and wear of the rubber.
