Liquid silicone rubber raw materials were extensively requisitioned in the 21st century. Regardless of the industry, liquid silicone rubber raw materials have a wide range of uses and play a crucial role. Narrowing down the scope can be seen in industries such as construction, healthcare, and light industry. If the scope is enlarged, it can be said that in terms of national security and national defense, it is like military aircraft flying in the sky or military tanks running on the ground. Below, we will introduce to you the types of silicone oil used in liquid silicone rubber.

Silicone oil usually refers to linear polysiloxane products that maintain a liquid state at room temperature. It is generally divided into two categories: methyl silicone oil and modified silicone oil. The commonly used silicone oil, methyl silicone oil, also known as ordinary silicone oil, has all organic groups of methyl. Methyl silicone oil has good chemical stability, insulation, and hydrophobic properties. It is prepared by hydrolysis of dimethyl dichlorosilane with water to obtain an initial polycondensation ring, which is then cracked and distilled to obtain a low ring. The silicone oil used in general silicone rubber is determined by its different types of silicone, therefore, the specific type of silicone oil used still depends on the silicone.

A two component additive liquid silicone rubber was prepared using vinyl silicone oil as the base material, hydrogen containing silicone oil as the crosslinking agent, white carbon black as the reinforcing agent, platinum catalyst, and restraint agent. The effects of the molar ratio of SiH in hydrogenated silicone oil to SiCHCH2 in vinyl silicone oil, hydrogenated silicone oil with different hydrogen contents and the same viscosity, and hydrogenated silicone oil with different viscosities and the same hydrogen content on the adhesive properties of two-component addition molded liquid silicone rubber were investigated.
