Will the high temperature affect the deformation of the O-ring? Let's follow the editor of FKM o-rings Manufacturers china to learn about it!

Temperature is an important factor affecting the relaxation of O-rings. No matter what kind of rubber material, long-term use at high temperatures will cause aging. The higher the temperature in the use environment, the greater the amount of deformation, and the O-ring will slowly The loss of elasticity when the product is deformed by more than 40% is followed by leakage. The O-ring will have initial stress before installation, but the initial stress will slowly degrade or even disappear with the long-term relaxation of the sealing ring and the influence of temperature. Some cases where the temperature drops sharply will also cause it to drop and then disappear. Even if the low temperature resistant rubber material is used, the stress generated at 20 degrees will not be greater than 25%, so the initial stress is set when installing the O-ring. And it is very important to fully consider the temperature factors in the environment.
The above is the editor of FKM o-rings Manufacturers china:A brief introduction to the knowledge that high temperature affects the deformation of O-rings.
