Dimethylsilicone oil is widely used as a lubricant in various industries due to its excellent thermal stability and low viscosity. It is commonly applied in mechanical systems, such as bearings and gears, to reduce friction and wear. In the automotive industry, it serves as a key component in brake fluids and shock absorbers, enhancing performance and longevity. Additionally, it is utilized in the production of personal care products, such as lotions and cosmetics, to provide a smooth, non-greasy texture. Its water-repellent properties make it ideal for use in waterproof coatings and sealants. In electronics, it acts as a dielectric fluid, protecting components from moisture and heat. Furthermore, it is employed in medical devices and pharmaceuticals for its biocompatibility and inert nature.
