What are the reasons for the aging of silicone foam gaskets?

 

Silicone foam gaskets have a wide range of applications. They are made of polymer materials and have good corrosion resistance. When used as truck pads, they reduce the wear and tear of trucks, and can also lift the goods. to a certain degree of protection. However, when using the silicone foam gasket, the protection of the foam gasket should be done well, so as to reduce the oxidation of the rubber gasket.

 

Reasons for the aging of silicone foam gaskets:

The aging phenomenon of the silicone foam gasket is due to its long-term heat, oxygen, light, mechanical force, radiation, chemical media, ozone in the air and other external factors, which cause chemical changes in the macromolecular chain and destroy the silicone gasket. original chemical structure, resulting in poor performance.

The external factors of the aging phenomenon of silicone foam gaskets mainly include physical factors, chemical factors and biological factors. Physical factors include heat, light, electricity, stress, etc.; chemical factors include oxygen, ozone, acid, alkali, salt and metal ions, etc.; biological factors include microorganisms and insects. In the aging process of rubber, these external factors often do not act alone, but influence each other to accelerate the aging process of silicone foam materials.

 

Different products have different effects of various factors under different conditions of use, and their aging conditions are also different. Even if the same product is used, the aging conditions are different due to different seasons and regions.
