金彩汇Sealing ring performance

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

金彩汇(1) elastic and resilient;

金彩汇(2) Appropriate mechanical strength, including expansion strength, elongation and tear strength, etc.

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

金彩汇(4) Easy to process and shape, and can maintain the precise size.

金彩汇(5) no corrosion of the contact surface, no pollution of the medium, etc.

The most suitable and commonly used material to meet the above requirements is rubber, so the sealing ring is mostly made of rubber material. There are many varieties of rubber, and there are constantly new varieties of rubber, design and selection, should understand the characteristics of various rubber, reasonable selection.
