1. The manufacturer of liquid silicone products introduces that silicone rubber is a highly saturated raw rubber, usually without sulfur vulcanization, thermal vulcanization is used, and thermal vulcanization uses organic peroxide as a vulcanizing agent. Therefore, raw rubber must not contain compounds that can decompose with peroxide The active substances (such as channel carbon black, certain organic accelerators and anti-aging agents, etc.) where the products act, otherwise it will affect the vulcanization.
2. According to the analysis of manufacturers of liquid silicone products, silicone products are generally used at high temperatures, and their compounding agents should be stable at high temperatures. For this reason, inorganic oxides are usually used as reinforcing agents.
3. Overview of manufacturers of liquid silicone products. Silica gel can easily cause the cracking and rearrangement of silicone under the action of a small amount of polar chemical reagents such as acid and alkali, which leads to a decrease in the heat resistance of silicone. So when choosing a compounding agent, its acid must be considered Alkaline, at the same time should also consider the acidity and alkalinity of peroxide cracking products, so as not to affect the performance of vulcanizate.
