Sealing ring performance
Elasticity and resilience
Appropriate mechanical strength, including expansion strength, elongation and tear resistance.
It has stable performance, is not easy to swell in the medium, and has small thermal shrinkage effect (Joule effect).
Easy to process and shape, and can maintain precise dimensions.
Does not corrode the contact surface, does not pollute the medium, etc.
The most suitable and most commonly used material to meet the above requirements is rubber, so sealing rings are mostly made of rubber materials. There are many varieties of rubber, and new rubber varieties are constantly emerging. When designing and selecting, you should understand the characteristics of various rubbers and make reasonable choices.
