Chemicals
The most common silicone oils are linear polysiloxane compounds, that orient in spiral chains, which easily glide and slip over one another. Silicone oils offer great thermal stability and flexible and flowable forms at extreme temperatures. Polydimethylsiloxane is the predominant silicone polymer made, but other organic groups (phenyl, vinyl, epoxide or amino) can be added to the siloxane polymer that can in some cases offer special characteristics or reactivity.
The repeating backbone of silicone oils and other siloxane polymers consists of alternating silicon and oxygen atoms. Silicone oils are comprised of linear repeating chains of silicon and oxygen, with each silicon atom also having two carbon-based substituents, which are most often methyl groups. The silicone oils can possess a degree of polymerization, in other words the average number of repeating siloxane groups in a polymer chain, ranging from several units to several thousand units. Replacing a small portion of the methyl groups with phenyl groups or amino functional groups can change how the siloxane polymers interact with other materials. Adding reactive organic groups to siloxane polymers can also allow for siloxane polymers to be integrated into various type of organic polymers, which can result in some unique properties when compared to standard organic polymers.
The viscosity of silicone oils can vary greatly from 0.65 cs to 2,000,000 cs and the viscosity remains constant across a wide range of temperatures. Silicone polymers also exhibit remarkable thermal stability (up to 250°C) when compared to some organic polymers, due to special characteristics of the chemical bonds between silicon and oxygen in the polymer chain. Silicones spread on surfaces very easily, due to their very low surface tension, and have high compressibility when compared to different hydrocarbon and mineral oils. Siloxane polymers have good dielectric properties and remarkable resistance to shear stress, natural ageing, oxidation, and hydrolysis.

Oil: liquid or half solid.
Both Oil and gum obtain resistance of high/low temperature, weatherability, waterproof, environment friendly, none toxicity and so on. Many of them are used as the raw materials of silicone rubber or other products.
Processability
Chlorosilanes to distillation and hydrolysis to prepolymer to chain extender to different oil types
Application/final products
As raw materials for silicone rubber or other materials. Silicone oils are primarily used as lubricants, heat transfer oil or hydraulic fluids.
Silicone oils are used in products you may use in everyday life. Let’s take a closer look at your facial tissues. Thanks to the excellent soft hand feeling and good hydrophilicity of some types of siloxane polymers, top grade facial tissues have been using silicone type softeners to improve the “soft feel” of tissues. Silicone oil improves the softness and silk-like smooth feeling of the tissues, with minimum impact on tissue strength.
Silicone type softener benefits:
The most common oils used in many applications are PDMS (polydimethylsiloxane). These inert oils are used as hydraulic or damping fluids, dielectric fluids, electronics-grade fluids, heating or cooling fluids, diffusion pump fluids, thermostatic fluids, paint additives and homecare product additives, lubricants and release agents. A certain number of these applications require the use of modified oils (e.g.* phenylated oils in order to increase heat stability), as well as solubility in organic systems and compatibility with organic compounds. Silicone oils are also widely used in cosmetics, pharmaceutical and medical applications.
