Vinyl silicone oils are linear polydimethylsiloxanes featuring terminal or pendant vinyl groups, serving as the core base polymer for addition-cure liquid silicone rubber. Through platinum-catalyzed hydrosilylation with methyl hydrogen silicone oil, they rapidly crosslink into elastomers. Low volatile content and narrow molecular weight distribution make them ideal for precision injection molding in baby care, medical devices, and electronic encapsulation, with additional use as reactive modifiers in coatings and adhesives. SUNOIT supplies customized grades across a range of viscosities and vinyl contents, backed by consistent quality to ensure reliable raw materials for addition-cure silicone products.
