Product performance

The selection of O-ring materials is of great significance to its sealing performance and service life. The performance of the material directly affects the performance of the O-ring. In addition to the general requirements of the sealing ring material, the O-ring should also pay attention to the following conditions:
(1) Elasticity and resilience;
(2) Appropriate mechanical strength, including expansion strength, elongation and tear strength, etc.

(3) Stable performance, not easy to swell in the medium, small thermal shrinkage effect (Joule effect).

(4) Easy to process and shape, and can maintain precise dimensions.
(5) No corrosion to the contact surface, no pollution to the medium, etc.
The most suitable and most commonly used material to meet the above requirements is rubber, so O-rings are mostly made of rubber materials. There are many types of rubber, and new types of rubber are constantly emerging. When designing and selecting, you should understand the characteristics of various rubbers and make reasonable choices.
