Vinyl silicone fluid has excellent high and low temperature resistance, lubricity, radiation resistance and compatibility. Vinyl silicone fluid is the main raw material for addition-molding liquid silicone rubber, silicone gel, etc. It is a modifier of the rubber compound, which can improve the cross-linking density, thereby increasing the tear strength, hardness and resilience. It can also be used as a plastic additive.
Vinyl silicone fluid reacts with various organic materials such as polyurethane and acrylic to produce better performance (weather resistance, aging resistance, UV resistance) new materials.
Vinyl silicone fluid by SiSiB, a professional silicone products manufacturer, includes vinyl-terminated polydimethylsiloxane (SiSiB® VF6030), vinyl-terminated polymethyl vinyl siloxane (SiSiB® VF6070), and vinyl phenyl silicone fluid. Different viscosities, vinyl content and phenyl contents are available upon request.
SiSiB® VF6030 vinyl terminated silicone polymers are used in addition cure systems. They can be used as base polymers or as blend polymers in order to create the desired hardness. These polymers can be cured with silicon-hydride crosslinkers and a platinum catalyst. They are available in a variety of viscosities.
SiSiB® VF6070, Vinylmethylsiloxane copolymers and vinyl T-structure fluids are mostly employed in peroxide cure silicones which involve peroxide induced free radical coupling between vinyl and methyl groups.
SiSiB® VF6031 is a Monovinyl Terminated Polydimethylsiloxane to reduce the durometer of the RTV formulation with minimal bleeding of fluid from the cured material. It may slow the curing of the RTV, but with the use of a faster platinum catalyst, it will help to accelerate the curing.
Vinyl phenyl silicone fluid can increase refractive index, improve radiation resistance, high & low temperature resistance. It is the important raw materials for LED silicone encapsulant.
