Divinyltetramethyldisiloxane / CAS NO. 2627-95-4

Organic Silicone , normally Chemical Organic Silicium which is known as Organic Silicone Chemicals, or Organosilicone Chemicals, are silicone compounds that contain Si-O bonds and have at least one organic group directly connected to a silicon atom.
Organic Silane / Silane Chemicals , or Organic Silane Chemicals the compound of silicon and hydrogen, is a general term for a range of Silicide Chemicals compounds, including silane (SiH4), ethyl silane (Si2H6) and some more advanced silicon hydrogen compounds.

We Wuhan Ruisunny Chemical Co., Ltd has been focusing on trading of such chemicals as Calcium Hypochlorite, Trichloroisocyanuric Acid, Ammonium Bicarbonate, Sodium Hydroxide , Hydrogen Peroxide and Silane etc. since 2007. We hereby have following details for the product as:

Divinyltetramethyldisiloxane is colorless or yellowish transparent liquid, unsoluble in water. It can be used as an intermediate in the production of addition type silicone rubber, molding silicone rubber, paper release agent, silicone gel, liquid silicone rubber, vinyl silicone resin, vinyl silicone fluid, platinum complex, etc.
