The main application of silicone oil
Application Sector Utilization Features Main Application Scope
Machinery industry High and low temperature resistance, anti-oxidation, strong shear resistance Used as lubricating oil for transmission, anti-vibration, damping oil, vacuum diffusion pump oil.
Electrical industry Dielectricity, heat resistance, hydrophobicity Used for insulation, heat resistance, moisture resistance and filling of transformers, capacitors, transistors, etc.
Chemical industry Low surface tension, good chemical stability Used as defoaming in chemical production processes such as fermentation, papermaking, and fabric dyeing.
Medicine Non-toxic, hydrophobic, surface active Medical defoamer, ointment and protective grease base, pharmaceutical additives, sterilization oil for surgical instruments, lubricant for artificial eyeballs.
General industry Anti-adhesive, weather resistance Used in coatings, rubber, plastic additives and internal mold release agents.
General industry Corrosion resistance, hydrophobicity Surface treatment of glassware, ceramics, paper, leather, metal, fabric, etc.
The decomposition of silicone oil in the natural environment is not due to the attack of bacteria like most organic compounds, but it can be said that it is decomposed into simpler molecules due to the catalysis of sand and gravel in the soil. The decomposition product is a ring-shaped organosilicon molecule, which evaporates into the air and further decomposes into natural products-water, CO2 and silicon dioxide water and matter. The organosilicon compound left in the soil is soluble in water, and is further decomposed into silicic acid under the irradiation of ultraviolet rays in the sun, and silicic acid is a compound naturally present in seawater, so there is no need to worry about the accumulation of silicone oil after a large amount of long-term use and residual.
