What are the uses of linear silicone oil? Do you know?
The main application areas of linear silicone oil market include: personal protection and cosmetics, medical and food, electrical insulation media, transportation equipment and instruments, lubrication, coating additives, etc.
Silicone oil application for personal protection and cosmetics:
Silicone oil is colorless, tasteless and non irritant. It has chemical stability, hydrophobicity, lubricity and storage stability, which are compatible with common cosmetics. In particular, the surface tension of silicone oil, good lubricating effect on the skin and moderate viscosity combine to make other components of cosmetics easily disperse and expand into films on the skin. Silicone oil containing lipstick, powder, eyelash oil, eye care oil, cosmetic pencil, nail polish and blush will not contain too much fat, promote the spread and distribution of cosmetic components, and extend the effective use time.
Medical and food silicone applications:
Defoaming, hydrophobicity and anti viscosity of linear silicone oil play an important role in medicine. It is mainly used in defoamer, antifogging agent, ointment and protective paste, medical additive, and as intraocular filler for vitrectomy, etc. Silicone oil can prevent water vapor from fogging on glass, and most antifogging agents on the market contain silicone oil. Such as glass antifogging agent, plastic film antifogging agent, etc. Using the characteristic of anti fog of silicone oil, a thin layer of silicone oil is coated on the objective lens at the front end of the electronic Rhinolaryngoscope to form a protective film. When the gas exhaled by the patient meets the objective lens at the front end of the mirror in the nasal passage during the examination, the water vapor is spread and becomes a thin layer of water film which is quickly evaporated without forming fog, playing the role of anti fog.
Silicon oil application of electrical insulating medium:
The electrical properties of linear silicone oil are not better than that of 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 range of temperature and frequency. Silicone oil has good compatibility with other insulating materials, so it is widely used in various transformers, capacitors, electronic equipment, components and devices, insulation cooling, impregnation, lubrication, nylon aid, coating and heat carrier of cable parts.
Silicone oil application for traffic equipment and instruments:
The properties of linear silicone oil, such as high and low temperature resistance, low viscosity coefficient, low vapor pressure, shear resistance, compressibility, non-toxic and tasteless, make it widely used as power transmission medium, working oil, buffer damping oil, brake oil, fluid coupling joint, lubrication and polishing, defoaming and water increasing agent in the transportation machinery and instrument industry.
Silicone oil applications for lubrication:
Linear silicone oil, especially dimethylsilicone oil and methylphenyl silicone oil, is suitable for lubrication of plastic (phenolic resin, nylon, polycarbonate), gear, bearing, shaft sleeve and rubber sealing ring, while for metal parts, it is only suitable for lubrication of synchronous motor, precision mechanical instruments and meters, and oil-bearing porous bronze bearing.
Silicone application of paint additives:
Linear silicone oil has small surface tension and unique interface property. Only a small amount of [0.0001% - 0.5% (mass fraction)] low viscosity dimethylsilicone oil is added to coatings and inks, which can effectively reduce the surface tension, improve the coating and expansibility, obtain orange peel free and uniform coating, and improve the dispersion of pigment and other auxiliaries in coatings and inks, so as to avoid them To separate, float, or precipitate.
