Organic Silicone, or Organosilicone Chemicals, are silicone compounds that contain Si-O bonds and have at least one organic group directly connected to a silicon atom.
Silicone Oil is a very important part of organic silicone compounds. It is a kind of linear polydimethylsiloxane with terminal hydroxyl, oily liquid with general performance of methyl silicone oil. It is usually called 107 silicone oil with  the viscosity  above 2500 cps. Besides the general properties of methyl silicone oil, it also has the reactivity of hydroxyl groups.

It is a transparent liquid with excellent electrical insulation and low temperature resistance, flash point and low freezing point.

It can be used as a silicone rubber based structure control agent, fabric based finishing agent and paper-based of antiadhevive agent.  The most widely used organicsilicone monomer in the production of DMC and D4 organic silicone products. The products can be used for a long time at - 50℃~+250℃.
