Silicone oil is one of the main products in the silicone industry. In recent years, in addition to dimethyl silicon oil, other various silicone oils continuous appeared.
But dimethyl silicon
oil is still the most important silicone oil products. Dimethyl silicone oil is
a transparent liquid, not easy to burn, has good thermal stability, low
volatility, low freezing point, good insulation, it also has waterproof and
chemically inert and other advantages.
Because of silicone oil has many excellent properties, so that it has extensive uses and
diverse. Be broadly divided into the following areas: in process additives,
silicone oil is widely used in the pressure system and some lubricant. Such as
be defoamers in the lubricant and the pressure oil, high vacuum equipments
lubricating and sealing, aviation good oils and lubrication of precision
machinery. It also can be used as release agents of vibration damping, used in
automobiles and aircraft shock absorber and torsional vibration Eliminator.
With a long chain chlorinated-phenyl and alkyl silicone oil, its lubricating
performance is better.
Paper handling, silicone oil is widely used in
paper processing. Paper through silicone oil treated will have excellent water
resistance. For example, book covers, calendars, paper, bread and sweets
cohesionless packed and liners, adhesive inserts, anti-pressure-sensitive
adhesive labels and so on, are processed by the silicone oil.
In textile industry was mainly using silicone oils
lubrication, smudge-proof and waterproof features to do some certain processing
on textiles. After fibers lubricated treated with silicone oil, can be reduced
breaking line when knitting, improving the texture of fabric. Waterproof
treated fabric is mainly used for waterproof clothing.
In the electrical and electronic industry, it is
largely to take advantage of silicone oils high resistivity, low dielectric
loss, insulation and non-combustibility and other natures. Make silicone oil
can be used as a coolant in vacuum tubes, rectifier and many electrical
components, as insulators in the capacitors and switch gear. Another potential
use is for larger transformer oil to replace the toxic polychlorinated
In other aspects, silicone oil for personal skin
care products originated in the United
States, has 49 years histories. In recent 10
years, its application developed faster. In 1991, silicon oils for cosmetic raw material in Japan
had 1450t. Now world consumption in this area has reached 20,000t per year.
Especially the low surface tension of silicone oil, has good lubrication for
the skin, combined with proper viscosity making other cosmetic component easy
to disperse and expanded into a film on the skin.
Use silicone oil to prepare skin-care products, not
only hydrate the skin, forming a layer of acid, alkali, salt, and organic
solvents and other protective coating, but also can maintain skins normal
breathing and treated dermatitis and eczema. Silicone oil in various vitamins,
fungicides have dissolution effect, cosmetics made it can form a very thin
layer of hydrophobic membrane on the skin surface, do not afraid of soaping,
effectively extending the role of nutritional cream and antibiotic cream. Added
silicone oil cream can protect the skin from the risks of pigments, solvents.
Equipped with silicone oil or other siloxane lipsticks, face powders, makeup,
Mascara, Nail polish, hair liquid, blusher and other makeup would not contain
too much fat, promoting the diffusion and distribution of cosmetics
ingredients, and extending its effective period.
