What is dimethicone?

201 Methyl silicone oil is a novel silicone synthetic material. The appearance is colorless and transparent oily liquid. Its chemical composition is straight-chain polymethylsiloxane with the structural formula:

Due to the stability of the silicone-oxygen bond and the hydrophobicity of methyl, as well as the structural characteristics of the methylsiloxane ensemble polymerization, the methyl silicone oil has good heat resistance. High flash point, non-volatile, viscosity coefficient is small, while the compression force is large, surface tension is small, chemical stability, good electrical (insulation), and water and moisture resistance, non-toxic effect on living organisms (including humans). In order to make methyl silicone oil in other objects on the surface of the formation of thin films or made of rubber-like solid material, can be heated at high temperatures (250-300 ℃) or add the appropriate catalyst (generally with peroxide) for curing treatment. The use of methyl silicone oil temperature range of 50-180 ℃.

Methyl silicone oil of different viscosity, their physicochemical properties and characteristics of the parameters also have certain differences. There are 201-10, 201-50, 201-100, 201-350, 201-500, 201-800, 201-1000 and other grades according to the viscosity of the product. According to the user’s requirements, we can also make other special viscosity specifications of the product.

Precautions

1, methyl silicone oil in heat, contact with acid or alkali has a certain destructive effect, methyl silicone oil in higher than 200 ° C in contact with air, oxidation can occur precipitation of corrosive formaldehyde and other low-boiling substances, methyl silicone oil, although the general temperature will not be spontaneous combustion, but to reach the combustion point (450 ° C – 500 ° C) or contact with the combustion caused by a large number of space filled with cotton-wool-like texture of silica (when the fire can be (when fire, can be suppressed with sand or wet sacks).

2, methyl silicone oil if the packaging storage is good, can not deteriorate for a long time (storage period of 5 years, after the re-examination, not found deterioration, can continue to name with).
