Silicone fluid, also known as silicone oil or polydimethylsiloxane (PDMS), is a type of fluid that is made of silicone, a synthetic polymer composed of silicon, oxygen, carbon, and hydrogen. It is known for its excellent heat resistance, chemical resistance, and electrical insulation properties. Silicone fluids are used in a wide range of applications, including lubricants, heat transfer fluids, insulation, and as a base fluid in personal care and cosmetic products. They are also used as a dampening fluid in shock absorbers, and in the manufacturing of silicone rubber products. Silicone fluids are available in different viscosity grades, from low-viscosity liquids to high-viscosity gels. They are also available in different purity levels and can be formulated with various additives to enhance specific properties. Silicone fluids have a very low toxicity and are considered to be safe for use in most applications. They are also resistant to oxidation and do not react with most chemicals, which makes them a versatile and long-lasting option for many industrial and consumer products.
