Sealing ring

requirement

In addition to the general requirements for sealing ring materials, the sealing ring should also pay attention to the following conditions:

(1) Rich in elasticity and resilience;

(2) Appropriate mechanical strength, including expansion strength, elongation, and tear resistance.

(3) Stable performance, not easily swollen in the medium, and small thermal shrinkage effect (Joule effect).

(4) Easy to process and maintain precise dimensions.

(5) Non corrosive contact surface, non polluting medium, etc.

The most suitable and commonly used material to meet the above requirements is rubber, so sealing rings are mostly made of rubber material. There are many types of rubber, and new rubber varieties are constantly emerging. When designing and selecting, it is important to understand the characteristics of each type of rubber and make a reasonable choice.
