Causes of Aging of Silica Gel Products

Most rubber and plastic colloid materials will basically have aging deformation phenomenon, and the aging problem of silicone products is also common with the precipitation of time and the influence of the use environment. Silicone accessories are mostly cosmetic. Use time is too long, affected by the environment, long-term distortion wear, will appear sticky, soft, appearance deformation, obvious hardening and other phenomena, shorten the service life. Cracking and breakage will occur after long-term use. So what causes the aging of silica gel products? The following changsheng silicone products manufacturers for you to introduce:

1, the effect of light and heat, increasing the temperature can cause thermal cracking or thermal crosslinking of silica gel products. But the basic function of heat is activation. Increase the oxygen diffusion rate and activation oxidation reaction, so as to accelerate the oxidation reaction rate of rubber, which is a universal aging phenomenon -- thermal oxygen aging.

2, the role of oxidation, oxygen in rubber with rubber molecules in free radical chain locking reaction, molecular chain fracture or excessive cross-linking, resulting in changes in the performance of silica gel products.

3, the cause of light wave, the shorter the light wave, the greater the energy. The damage to rubber is caused by higher energy ultraviolet light. In addition to directly causing the fracture and crosslinking of rubber molecular chain, ultraviolet radiation can produce free radicals by absorbing light energy, which can trigger and accelerate the oxidation chain reaction process.

4, the role of ozone, ozone chemical reactive oxygen is much higher, more destructive, it is also to make molecular chain fracture, but the effect of ozone on rubber with rubber deformation or not is different.

5, the role of water, the role of water has two aspects: silica gel products in the wet air rain or soaked in water, easy to destroy, this is because the water-soluble substances in silica gel and water tsuen group and other components are extracted and dissolved by water.

Silica gel products have the characteristics of high temperature resistance, easy cleaning, long life, soft and comfortable, diverse colors, environmental protection, non-toxic, electrical insulation performance, low temperature resistance, electrical conductivity, weather resistance, thermal conductivity, radiation resistance and so on.
