Factors that lead to aging silicone tube

1. The chemical activity of ozone is high and more destructive. It also breaks the molecular chain, but the effect of ozone on rubber is different from the rubber deformation. When the rubber acting for deformed is mainly unsaturated rubber), the cracks that are straight with the direction of stress, the so -called "ozone cracks"; when the rubber acts on the deformation, only the oxidation film is generated on the surface without cracking.

2. There are two aspects of water: rubber is easily damaged when the wet air is rained or soaked in the water. This is because the water -soluble substances and the ingredients of Qingshui Tsui Tuan in the rubber are dissolved by water. Causes of hydrolysis or absorption. Especially under the alternation of water soaking and atmospheric exposure, the damage of rubber will be accelerated. However, in some cases, moisture does not afford to destroy rubber, and even delay aging.

3. Oxygen response to the linked base chain lock with rubber molecules in the rubber, and the molecular chain breaks or overlap, causing changes in rubber performance. Oxidation is one of the important reasons for the aging of rubber.
