Silicone: Application of silicone products

Silicone products have good resistance to high and low temperatures, and can generally work for a long time at 180 ° C. Silicone rubber can also work for a long time at 250 ° C, and can withstand high temperature of more than 1000 ° C instantaneously. Silicone material has good low temperature resistance and can generally work at -55 ° C. Some silicone rubber is still elastic at -110 ° C. Silicone materials have good electrical insulation properties, and the dielectric properties do not change dramatically with the change of temperature. The dielectric constant does not increase with the increase of frequency. And arc resistance, corona resistance, leakage resistance; Ozone resistance, radiation resistance, weather resistance, flame resistance, so it is very widely used.
There are many categories of silicone products, which can be roughly divided into five categories。
1. The most commonly used high temperature vulcanized silicone rubber are methyl vinyl silicone rubber, cold resistant phenyl silicone rubber, oil resistant, solvent resistant fluorine silicone rubber and nitrile silicone rubber, radiation resistant benzylene silicone rubber and so on. For the convenience of use, the compound is often prepared and provided to the user.

2. Room temperature vulcanized silicone rubber has two components and one group according to the packaging form. The two components are divided into methyl, phenyl, nitrile-silicane, fluoro-silicane and phenylene. The single component is divided into deacid type, dealcohol type, deoxime type, deamine type, deamide type, deketone type and so on.

3. Silicone oil Silicone oil can be divided into methyl silicone oil, ethyl silicone oil, methyl phenyl silicone oil, amino silicone oil, methyl hydrogen silicone oil, chlorophenyl silicone oil, fluorine silicone oil, nitrile silicone oil, long chain paraffin silicone oil, diffusion pump oil and modified silicone oil. There is a large amount of silicone oil processing products, that is, silicone oil emulsion, such as fabric treatment agent is an example.

4. Silicone resin according to the composition can be divided into methyl silicone resin, methyl phenyl silicone resin; According to the form can be divided into solvent-based, solvent-free. Silicone resins are also used for coating, molding powder and modification.

5. Silane coupling agents are classified according to functional groups, silane coupling agents mainly include vinyl silane, amino silane, epoxy silane, sulfhydryl silane and methylacryloxy silane.
