Everyone knows that the most important thing about the aging of rubber sealing strips is the phenomenon of cracks, hardening, discoloration, cracks, etc. that occur when the rubber is bought or used during storage.

The main factor that affects the aging of the sealing strip is the influence of the natural environment. First, the influence of air components such as oxygen, because the oxidation reaction causes the molecular chain of the rubber to break, but the degree of influence of ozone and oxygen is not the same Yes, the oxidative destructiveness of ozone will be greater. The second aspect is the influence of light and moisture, which are the key factors to accelerate aging. Moisture in the air is the most important condition that causes the rubber to soften. However, light is the most important factor that promotes its discoloration. Long-term sunlight exposure It is easy to deform and soften the rubber. Finally, the temperature, temperature has a greater impact on rubber, mainly in the cold winter will harden the rubber severely will cause the rubber to break, the hot summer will soften the rubber.

The above points are the most important factors that promote the aging of rubber seals. Therefore, when maintaining the seals, you should start from the above aspects of waterproofing, air isolation and thermal insulation.
