What are the uses of linear silicone oil?

The main market applications of linear silicone oil include: personal protection and cosmetics, medical and food, electrical insulating media, transportation equipment and meters, lubrication, paint additives, etc.
Application of silicone oil for personal protection and cosmetics:
Silicone oil is a colorless, odorless, and non-irritating product. It has chemical stability, water repellency, lubricity and storage stability. It is compatible with commonly used cosmetics. In particular, the surface tension of silicone oil, the good lubrication effect on the skin, and the moderate viscosity combine to make the other components of the cosmetics easy to disperse and expand into a film on the skin. Cosmetics such as lipstick, pressed powder, mascara, eye circle dye, makeup pen, nail polish and blush with silicone oil will not contain too much oil, promote the diffusion and distribution of cosmetic components, and extend its effective use time.
Medical and food silicone oil applications:
The defoaming, hydrophobic and anti-sticking properties of linear silicone oil play an important role in medicine. Mainly used in medical defoamers, antifogging agents, ointments and protective ointments, medicinal additives and as intraocular fillers for vitreous cutting, etc. Silicone oil can prevent water vapor from fogging on the glass. Most anti-fogging agents on the market contain silicone oil. Such as glass antifogging agent, plastic film antifogging agent, etc. Utilizing the anti-fogging feature of silicone oil, a very thin layer of silicone oil is applied to the objective lens at the front end of the electronic rhinopharyngolaryngoscope to form a protective film. When the patient's exhaled air meets the objective lens at the front end of the mirror in the nasal passage , The water vapor is spread and becomes a thin and tiny water film which is quickly evaporated without forming fog, which plays a role of anti-fog.
Silicone oil application for electrical insulating medium: linear silicone oil has no better electrical properties than general insulating oil, but its viscosity range is wide, dielectric loss is small, flash point and ignition point are high, and it can maintain good dielectric properties in a wide temperature and frequency range . Silicone oil has good compatibility with other insulating materials, so it is widely used as insulation cooling, dipping, lubrication, dipping, coating and heat carrier of various transformers, capacitors, electronic equipment, components and devices, and cables.
Silicone oil application for transportation equipment and meters:
Linear silicone oil's high and low temperature resistance, low temperature viscosity coefficient, low vapor pressure, shear resistance, compressibility, non-toxic, and odorless properties make it widely used as a power transmission medium, working oil, and buffer in the transportation machinery and instrument industry. Damping oil, brake oil, fluid coupling, lubrication and polishing, defoaming and water increasing agent, etc.
Lubricated silicone oil application:
Linear silicone oil, especially dimethyl silicone oil and methyl phenyl silicone oil are suitable for the lubrication of plastics (phenolic resin, nylon, polycarbonate,) gears, bearings, bushings and rubber seals, etc., for metal parts only Synchronous motors, precision mechanical instruments and meters, lubricated with oily porous bronze bearings.
Silicone oil application of paint additives:
Linear silicone oil has low surface tension and unique interface properties. Only a small amount of [0.0001%-0.5% (mass fraction)] low viscosity dimethyl silicone oil is added to coatings and inks to effectively reduce the surface tension. Improve the coatability and expandability to obtain a coating with no orange peel and uniform appearance. It can also improve the dispersion of pigments and other additives in coatings and inks, and avoid their segregation, floating or precipitation.
