Where is the dimethylsilicone oil used?
201 methyl silicone oil is a novel silicone synthetic material. The appearance is colorless transparent oily liquid. Its chemical composition is straight chain polymethylsiloxane, the structural formula is:
Because of the stability of silico-oxygen bond, hydrophobicity of methyl group and the structure of methicone polymerization, the methicone oil has good heat resistance. High flash point, non-volatile, small viscosity coefficient, large compression force, small surface tension, chemical stability, good electrical (insulation), and water and moisture resistance, non-toxic to organisms (including humans). In order to make methyl silicone oil form a film on the surface of other objects or make a rubber-like solid substance, it can be heated at high temperature (250-300 ° C) or cured with an appropriate catalyst (generally with peroxide). The temperature range of methyl silicone oil is 50-180℃.
The physical and chemical properties and characteristic parameters of methyl silicone oils with different viscosity are also different. The product is divided by viscosity, there are 201-10, 201-50, 201-100, 201-350, 201-500, 201-800, 201-1000 and other brands. It can also be made into other products with special viscosity specifications according to user requirements.
Dimethylsilicone oil
In what fields can it be used?
Scope of application:
1, in electrical and electronic industries for temperature resistance, arc resistance, corrosion resistance, moisture insulation medium.
2, in chemical, pharmaceutical, food and other industrial sectors as an excellent heat carrier.
3, in synthetic resin, oil processing, food manufacturing, as well as fermentation, paper and other processes as efficient defoamer.
4, used in precision machinery and instruments for shockproof, damping, lubrication, force transfer, etc.
5, in plastic and rubber molding processing, as well as food production as a high temperature release agent.
6, in glass, ceramics, metal, leather, fabric, silk and cement products and other materials as surface treatment agent, in order to achieve enhancement, drainage corrosion resistance, mildew, smooth and other effects.
7, in paint, grease, cosmetics and other products as an additive, to improve the smooth, smooth and other properties.
8, in the medical, such as surgery, wound dressing, injection treatment, blood storage and oral medicine, it has many uses.

Matters needing attention
1, methyl silicone oil in the heat, and acid or alkali contact has a certain destructive effect, methyl silicone oil in contact with the air above 200℃, can occur oxidation precipitation corrosive formaldehyde and other low boiling matter, methyl silicone oil although at the general temperature will not spontaneous combustion, but reach the combustion point (450℃-500℃) or contact cause combustion, Fill the space with a large amount of cotton-like silica (in case of fire, it can be crushed with sand or wet gunny bags).
2, if the packaging and storage of methyl silicone oil is good, it can be durable without deterioration (storage period is tentatively set at 5 years, overdue can be rechecked, no deterioration is found, it can continue to be named).
