What is vinyl silicone oil
Hits: 798

Structural characteristics: Mainly 2 or more silicon-vinyl-vinyloxanes. It is usually a linear organic silicon polymer having a vinyl in both ends of the polymer chain, and some contain a small amount of silicon-vinyl link in the middle of the polymer chain. The most typical base polymer of the application is α, ω-divinyl polymethylsiloxane (end vinyl silicone)
Exterior
The main characteristics of vinyl silicone oil are colorless, tasteless, non-toxic, and non-volatile liquids, insoluble in water, can be solubilized with benzene, dimethyl ether, methyl ethyl ketone, tetrachlorocarbon or kerosene, slightly soluble in acetone. Ethanol. It has a small vapor pressure, a higher flash point and a combustion point, and the lower coagulation point has different molecular weight, and the viscosity is also increased as the number N of the segment is increased, and the viscosity is also increased, so the vinyl silicone oil can have a variety of different viscosity. It is widely used in the addition of silicone rubber production to enhance the strength and hardness of silicone rubber. It is used to make liquid silicone rubber, which is the main material of injection molded silicone rubber and addition electron potting glue and production ink, additional sealing gum.
Mainly divided into terminal vinyl silicone and high vinyl silicone oil
Ethylene silicone oil
It is a double vinyl-terminated polydimethylsiloxane. The product is stable, and the volatilization is low, and is a major raw material, silicone oil, silicone gel, or the like, the modifier.
High vinyl silicone oil
It is a double vinyl block or a methyl-block and the intermediate link contains a vinyl polydimethylsiloxane. The product quality is stable, low volatile, no yellow change. It is the main raw material of the addition liquid silicone rubber, silicone irrigation, silicone gel or the like; modifier of mixing rubber; plastic additive, etc.
We develop double-ended vinyl silicon oil ends for market demand, with good reaction activity, can be crosslinked with hydrogen-containing silicone oil or the like. Due to the different vinyl content of the viscosity, add other catalysts, auxiliaries, suitable for fabricating different hardness and different mechanical properties required for additional liquid silicone rubber. In addition, other viscosity, other vinyl content of other vinyl content can be carried out in accordance with customer needs.
