Dimethylsilicone oil is widely used as lubricant for extruding rubber products such as conveyor belt. It can be used as lubricant in the following textile processes: yarn weaving, thread lubrication, socks and underwear production, thread needle lubrication, glass fiber filter screen.

silicone oil has the characteristics of small viscosity temperature coefficient, heat resistance, oxidation resistance, shear resistance and so on. Common lubricating oils, such as petroleum and diesters, will lose their effectiveness in high or low temperature environment, which is mainly due to low oxidation resistance and easy decomposition into acids. Colloid, colloid and carbon particles sometimes form a hard thin layer and adhere to the bearing, causing bearing corrosion or damage. The types of silicone oil, that is, the types of organic groups attached to silicon atoms, have a great influence on the lubricity of silicone oil. The lubricity of methyl silicone oil is poor, and the lubricity can be improved by introducing phenyl or halogenated phenyl.

The load capacity of methyl silicone oil film is poor, but it is the best when engineering plastics such as phenolic resin and polyoxalamide are used as bearing materials; however, it has no moistening property in the bearing composed of steel and steel, so the lubricity also depends on the combination of bearing metal. In short, the bearing metal for lubrication should be selected, and the load should not be too high.

High temperature grease made of methylcyanophenyl silicone oil and organometallic compounds. It has excellent oxidation resistance. It hardly oxidizes at 265 ℃ and can be used for a long time at 300 ℃.

Silicone oil can be used as a film remover, its surface tension is small, easy to form a thin film on the mold. It has little compatibility with most polymers, so it has good demoulding property. Silicone oil has good heat resistance, so the mold release agent has a long service life and can reduce the mold pollution. Even at high temperature, carbonization does not produce smoke or any toxic gas, so silicone oil is an ideal release agent.

In addition to the rubber products, a variety of Plastic molding processing, in food, metal casting, metal welding, glass products, printing and other industries also have a very wide range of applications. Because the silicone oil is non-toxic, it can contact with food directly and can be used as the release agent of food baking mold.

High viscosity silicone oil can also be directly added to plastics as processing aid and internal release agent, which can improve the demoulding performance of plastics, improve the production efficiency and reduce the wear of tools, molds and equipment. Silicone oil can also be directly added to silicone rubber to make copier fixing roller and so on.
