Discover Aure Chemical's Premium D4Vi Supply
Tetramethyltetravinylcyclotetrasiloxane (D4Vi) is a vital cyclic organosilicon compound with the chemical formula [(CH₃)(CH₂=CH)SiO]₄. It features a four-membered siloxane ring with four methyl groups and crucially, four reactive vinyl groups attached to the silicon atoms. D4Vi presents as a clear, colorless, and odorless liquid. The presence of multiple vinyl groups makes D4Vi an exceptionally reactive monomer, serving as a critical building block for synthesizing a wide range of high-performance silicone materials.
