Silicone oil has many special properties, such as low temperature viscosity coefficient, resistance to high and low temperatures, oxidation resistance, high flash point, low volatility, good insulation, low surface tension, no corrosion to metals, non-toxic, etc. Due to these characteristics, silicone oil has excellent performance in many applications. Among various silicone oils, methyl silicone oil is the most widely used and the most important type, followed by methyl phenyl silicone oil. Various functional silicone oils and modified silicone oils are mainly used for special purposes.
Character: Colorless, odorless, non-toxic, and non volatile liquid.
Usage: It has various viscosities. It has high heat resistance, water resistance, electrical insulation, and low surface tension. Commonly used as advanced lubricating oil, shockproof oil, insulation oil, defoamer, release agent, polishing agent, isolation agent, and vacuum diffusion pump oil; Lotion can be used for car tire polishing, instrument panel polishing, etc. Methyl silicone oil is the most commonly used. A smooth and soft tactile finish applied to textile finishing after emulsification or modification. Emulsified silicone oil is also added to the shampoo of daily care products to improve the lubrication of hair. In addition, there are ethyl silicone oil, methylphenyl silicone oil, nitrile containing silicone oil, polyether modified silicone oil (water-soluble silicone oil), etc.
The application range of silicone oil is very extensive. It is not only used as a special material in aviation, cutting-edge technology, and military technology departments, but also in various sectors of the national economy. Its application scope has expanded to: construction, electronics and electrical, textiles, automobiles, machinery, leather and paper making, chemical and light industries, metals and paints, medicine and medical treatment, and so on.
The main applications of silicone oil and its derivatives are film remover, shock absorber oil, dielectric oil, hydraulic oil, heat transfer oil, diffusion pump oil, defoamer, lubricant, hydrophobic agent, paint additive, polishing agent, cosmetics and daily Household goods additive, surfactant, particle and fiber treatment agent, silicone grease, flocculant.
Advantages:
(1) The viscosity temperature performance is the best among liquid lubricants, with small viscosity changes over a wide temperature range. Its solidification point is generally less than -50 ℃, and some can reach as high as -70 ℃. When stored for a long time at low temperatures, the appearance and viscosity of the oil remain unchanged. It is a base oil that takes into account high, low, and wide temperature ranges.
(2) Excellent thermal oxidation stability, such as thermal decomposition temperature>300 ℃, small evaporation loss (150 ℃, 30 days, evaporation loss only 2%), oxidation test (200 ℃, 72 hours), small changes in viscosity and acid value.
(3) Excellent electrical insulation, volume resistance, etc. do not change within the range of room temperature to 130 ℃ (but oil cannot contain water).
(4) It is a non-toxic, low foaming, and strong anti foaming oil that can be used as a defoamer.
(5) Excellent shear stability, with the function of absorbing vibration and preventing vibration propagation, can be used as a damping fluid.
