How to alleviate aging of silicone products

Due to the environmental safety, low price and long service life of silicone rubber products, a variety of silicone rubber products have taken a part in the market.

In most people's minds, silicone products have excellent performance and good tear resistance and stretching experience. However, many old customers will find a problem after using silicone products for a long time, that is, silicone products will slowly age, and there is no elastic adhesive. So silicone products have always been good in performance. Why do they age? What is the cause?

The adhesion of silicone resin is higher than that of many rubbers. However, silicone products, like products made of other materials, will also experience aging. This is because the internal molecular chain breaks, which greatly changes the performance of silicone. For rubber products, the silicone is most afraid of ultraviolet radiation, which will directly lead to the breakage of silicone molecular chain. This is because rubber and plastic products can absorb light energy, Free molecules are produced in rubber.

The first point that leads to the aging of silicone products is that the service life is too long, which is relatively rare. As long as silicone products do not need sharp knives to break it, or are used in other unsuitable scenarios, they can be used for at least 10 years, and the longest time can be up to 100 years under unconventional circumstances.

Frequent use at high temperature or in high temperature environment for a long time will accelerate the oxidation environment of silicone rubber products and cause aging.

Therefore, when using silicone rubber products, we should try to avoid long-term use in the environment of high temperature and pressure, chemicals and ozone, so as to effectively alleviate the aging of silicone rubber products, thus improving the service life of silicone rubber products.
