At present, silicone oil is mainly used as advanced lubricating oil, shockproof oil, insulating oil, defoaming agent, demoulding agent, polishing agent, isolator and vacuum diffusion pump oil, etc. Emulsion can be used for car tire glazing, dashboard glazing and so on.

1. Daily chemical industry:
Silicone emulsion has been widely used in cosmetics, adding the right amount of products can make cosmetics have the advantages of lubrication, sunlight and ultraviolet radiation resistance, good air permeability, etc. At the same time, because of the hydrophobic properties of silicone oil, can improve the waterproof and sweat resistance of cosmetics.

2. Textile Industry:
Silicone oil in textile and garment industry can be used as fabric softener, lubricant, waterproof agent, finishing agent and so on. To meet the high-end needs of textiles, chemical manufacturers are also developing silicone oils that can be used with a variety of functional additives such as waterproofing, flame retardants, antistatic agents, color fixing agents and so on. In addition, in order to improve the performance of the fabric, there are silicone products that can be used in the same bath with dyeing, cotton silicone oil with cool feeling, silicone products that can improve the feel of the fabric, and silicone darkening agents that can give the fabric excellent darkening effect, good storage stability, does not affect the color fastness, feel good, etc. In addition to functional textiles as additives in textiles, silicone products will also be used in other areas of textiles, such as silicone and polyurethane combination to form fabric coating; Printing of fabric formed by polymerization of silicone and acrylic acid; Organic silicon and organic fluorine combined to form waterproof coating on fabric surface.

3, mechanical
Damping: silicone oil is widely used in motors, electrical appliances, electronic instruments as temperature resistance, arc corona resistance, corrosion resistance, moisture-proof, dustproof insulating medium, currently also used as transformers, capacitors, TV scanning transformer impregnation agent. In all kinds of precision machinery, instruments and meters, used as liquid shock proof, damping material. Because the damping performance of silicone oil is little affected by temperature, it is mostly used in instruments with strong mechanical vibration and large temperature changes, such as aircraft and automobile instruments. Used for shock, damping, stable instrument reading, also as a liquid spring, and in aircraft landing gear.

Thermal conductivity: thermal silicone grease is the most widely used thermal conductivity medium at present. It is a kind of ester formed after heating, decompression, grinding and other processes by using silicone oil as raw material and adding thickeners and other fillers. The material has a certain viscosity and no obvious granular feeling. Thermal silicone grease operating temperature is generally -50℃ ~ 180℃, it has good thermal conductivity, high temperature resistance, aging resistance and waterproof characteristics. In the heat dissipation process of the device, after heating to a certain state, the thermal grease will present a semi-liquid state, fully fill the gap between the CPU and the heat sink, make the joint between the two more closely, and then strengthen the heat conduction. In general, thermal silicone grease is insoluble in water, not easy to be oxidized, but also has a certain lubricity and electrical insulation. Like thermal silicone grease, thermal silicone is also made of silicon oil with certain chemical raw materials, and through chemical processing. But different from thermal silicone grease, there are some sticky substances in the chemical raw materials added to it, so the thermal silicone product has a certain adhesion. Thermal silica gel is the biggest characteristic of hard texture after solidification, its thermal conductivity is slightly lower than thermal silicone grease.

Demoulding: because of its non-viscosity with rubber, plastic and metal, silicone oil can be widely used as a demoulding agent for various rubber and plastic products forming and processing. Its advantage is convenient demoulding and making the surface of products clean, smooth and clear texture.

4. Medical and food industries
The commonly used medical silicone oil is mostly polydimethylsiloxane, which can be made into anti-bloating tablets for abdominal distension and aerosol for pulmonary edema by its defoaming property. It can also be used as an anti-adhesive agent to prevent intestinal adhesion in abdominal surgery, as an anti-foaming agent for gastric juice in gastroscopy and as a lubricant for some medical surgical instruments. Silicone oil can also be used as silicone defoaming agent in the food industry, special polysiloxane resin in the emulsified products, other can be directly oil type products, such defoaming occasions include fermentation and sugar production, and other food production process foam suppression. Silicone grease is an organic silicone grease made of food grade silicone oil thickened by inorganic thickener, and refined with anti-oxidation, anti-corrosion and other additives. Food grade silicone design for sealing lubrication of food processing equipment. Does not contain any toxic substances and heavy metals, absolutely safe for food.

5, surface treatment
Mainly used for glass fiber material waterproof, antifouling, waterproof performance is excellent. Building materials treated with silicone oil can improve their wind resistance and hydrophobicity. By mixing 0.1% to 0.15% (mass fraction) or higher solid content silicone oil emulsion into the mortar, the above characteristics can be demonstrated and the mortar smoothness and fluidity can be improved. Asbestos, cement, gypsum board can also use silicone oil treatment.

6. Defoaming agent
Silicone oil is widely used as defoamer. In the textile printing and dyeing process, such as sizing, desizing refining, bleaching and dyeing added as defoaming agent; In the petrochemical industry drilling, oil and gas separation, demulsification, oil refining section, as well as lubricating oil, cutting fluid added use; Used in paper industry and paint ink; Silicone defoamer used in detergent industry; There are silicone defoaming agents used in the food industry mentioned above.
