Vinyl silicone oil CAS NO: 68083-19-2

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.
Silicone Oil or Silicone Fluid Chemicals refers to linear polysiloxane products that remain liquid at room temperature. It is divided into two Types Of Silicone Oil: methyl silicone oil and modified silicone oil. The most commonly used silicone oil is methyl silicone oil, also known as ordinary Silicone Based Oil , its organic groups are all methyl, and the silicone oil that uses other organic groups to replace some methyl groups is called modified silicone oil. Silicone Lubricating Oil would be most common application for the product.

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:

Vinyl silicone oil can mainly have terminal vinyl dimethicone (Vi-PDMS) and end-vinyl polymethyl vinyl siloxane (Vi-PMVS). It is widely used as a binder for the production of high-temperature vulcanized silicone rubber (HTV), and is mixed with crosslinking agents, reinforcing agents, colorants, structural control agents, aging agents, etc.

3)      Uses:

Vinyl silicone oil is used as a binder for the production of high-temperature vulcanized silicone rubber (HTV), and is mixed with crosslinking agents, reinforcing agents, colorants, structural control agents, aging agents, etc. to prepare high-temperature vulcanized silicone rubber;  And it can be used to make liquid silicone rubber, which is the main material for injection thermoformed silicone rubber; Another vinyl silicone oil can react with such as polyurethane, and other material, to obtain superior performance (weather resistance, aging resistance, ultraviolet resistance, enhanced toughness, etc.) of new materials (such as coatings are an important raw material for the production of various coatings and modified silicone oil and other products. )
