Vinyl Silicone Oil for HTV Silicone Rubber

Vinyl Silicone Oil can mainly have terminal vinyl dimethicone (Vi-PDMS) and end-vinyl polymethyl vinyl siloxane (Vi-PMVS). This is important in the production of high temperature vulcanised silicone rubber (HTV silicone rubber) as it needs to be cross-linked to achieve the final properties.Vinyl silicone oils are known for their low viscosity, which can range from below 10 centiStokes (cSt) to over 10,000 cSt. The viscosity of the oil can be adjusted by changing the molecular weight, which will affect the flow characteristics and other properties of the oil. 
Vinyl silicone fluids are available in a range of molecular weights, which may affect their viscosity and other properties. Typically, vinyl silicone oil products are available in molecular weights ranging from 1000 to 100,000 g/mol.

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. )
