A unique silicone compound – Dimethicone Oil
1, what is dimethicone oil?
Dimethicone, also known as polydimethylsiloxane, is a colorless, odorless, non-toxic, non-volatile liquid. It is hydrolyzed by dimethyl dichlorosilane and water to produce the initial condensation of the ring body, the ring body by cracking, distillation of the low ring body, and then the ring body, capping agent, catalyst together with the polymerization of a variety of different degrees of polymerization of the mixture can be obtained by decompression distillation to remove low-boiling material can be produced methyl silicone oil.
2、Characteristics of dimethyl silicone oil
Because of its unique chemical structure, dimethicone oil shows the following series of excellent performance:
Excellent thermal stability: dimethicone oil remains stable at high temperatures and is not easy to decompose or produce harmful substances.
Good resistance to combustion: its high flash point and non-flammable properties make dimethicone a significant advantage in environments requiring fire protection or high temperatures.
Good electrical insulation: the high resistivity and low dielectric constant of dimethicones make them ideal for use as electrical insulation materials.
Low freezing temperatures: Dimethicones maintain their fluidity and stability even at very low temperatures.
Low surface tension: it makes dimethicone oil spread easily on the surface of the object and form a uniform lubricating film, which plays a good lubricating and isolating role, and is suitable for use as a lubricant and surface treatment agent.
Higher compression resistance: it can withstand greater pressure without being easily deformed, and its stability and reliability in high-pressure environments are suitable for application scenarios that require high compression.
Good oxidation resistance: Even in long time use, dimethicone oil can maintain good performance and is not easy to be oxidized.
Weathering resistance: Dimethicone fluids have good resistance to UV, ozone and other environmental factors, and can maintain stable performance for a long time.
Viscosity with temperature change is small: dimethicone oil viscosity is less affected by temperature, making it in different temperature conditions can maintain stable performance.
