Silicone rubber is mainly divided into room temperature vulcanized silicone rubber, high temperature vulcanized silicone rubber, silicone rubber by silicon, oxygen atoms to form the main chain, side chain for carbon groups, the largest dosage is the side chain for ethylene silicone rubber. Both heat and cold resistance, the use of temperature between 100- 300℃, it has excellent weather resistance and ozone resistance with good insulation. Disadvantages are low strength, poor tear resistance, wear resistance is also poor.
Silicone resin is a semi-inorganic polymer with silicon - oxygen - silicon as the main chain, and the silicon atom is connected with an organic group. Polysiloxane, a highly branched polymer (in contrast to linear silicone oil) with a highly cross-LINKED structure, solidifies into a solid. With the dual characteristics of organic resin and inorganic materials, it has unique physical and chemical properties.
Silicone oil usually refers to linear polysiloxane products that remain liquid at room temperature. Generally divided into methyl silicone oil and modified silicone oil two categories. The most commonly used silicone oil - methyl silicone oil, also known as ordinary silicone oil, its organic groups are all methyl, methyl silicone oil has good chemical stability, insulation, good hydrophobic performance. It is hydrolyzed by dimethyl dichlorosilane to produce the initial POLYcondensation ring, the ring by cracking, distillation to produce the low ring, then the ring, head agent, catalyst together polymerization can get a variety of mixtures of different degrees of polymerization, by reducing pressure distillation to remove the low boiling content can be produced silicone oil.
