a, w - dihydroxy polydimethylsiloxane

INTRODUCTION OF 107 Α,Ω- DIHYDROXYPOLYSILOXANE

α,ω- Dihydroxypolysiloxane is a basic rubber of two-component and one component condensed silicone rubber, which is usually called 107 rubber in the market. Raw rubber can be directly used as a commodity, and can be used as an intermediate to produce various condensed silicone rubber products.

IS 107 GLUE POLYSILOXANE?

107 silicone rubber is polysiloxane, which is usually called 107 rubber in the market. The raw rubber can be directly used as a commodity, and can be used as an intermediate to produce various condensed silicone rubber products. Room temperature vulcanized silicone rubber This is a special rubber that can be vulcanized at room temperature. Its chemical composition is polydimethylsiloxane, with hydroxydimethylsiloxy as the terminal group. The silicone rubber formed by vulcanization in the greenhouse of this product has excellent insulation, arc resistance, corona resistance, water resistance and weather aging resistance ℃ - 250 ℃. It is used in the range of waterproof, dustproof and cold proof.

107 MOLECULAR STRUCTURE

Silicone rubber is a kind of organic silicon material, polymerized from siloxane monomer, with hydroxyl group at the end of the molecule.

Its structure is as follows: HO Si (CH3) 2 O [Si (CH3) 2 O] nSi (CH3) 2 OH

Its chemical name is a, w - dihydroxy polydimethylsiloxane, and its viscosity is generally 2500mPa.S Above, hydroxyl silicone oil is called 107 silicone rubber. In addition to the general properties of methyl silicone oil, this product also has hydroxyl reaction activity. It can be used to make some new materials, or cross-linked into elastomer (or membrane).

CHARACTERISTICS OF HYDROXYL TERMINATED POLYDIMETHYLSILOXANE

1. 107 Silicone rubber is a kind of organic silicon product, which is a colorless transparent flowing liquid, and is viscous. Its chemical name is hydroxyl terminated polydimethylsiloxane.

2. In addition to the general properties of methyl silicone oil, silicone rubber also has the reactivity of hydroxyl group. It can be used to manufacture some new materials or cross-linked into elastomer (or membrane).

3. 107 Silicone rubber has excellent electrical insulation and high and low temperature resistance, high flash point, low freezing point, up to - 50 ℃~+250 ℃ for long-term use, low viscosity temperature coefficient, high compressibility, low surface tension, and good hydrophobicity.
