CAS NO. : 68951-99-5 Vinyl Silicone Fluid (Vinyldimethylsiloxy Term)

Synonyms: Vinyl Terminated Polydimethylsiloxane, Vinyl terminated silicone fluid, α、ω Vinyl silicone fluid, Vinyl terminated PDMS, Vinyl Silicone Oil.
CAS 68951-99-5 Silicone Fluid is straight chained polydimethylsiloxane terminated by vinyl group. As there is fair quantity of relatively active vinyl group in the molecule, It’s an excellent and lively intermediate material. Two ends of vinyl have very strong reactivity, can have addition reaction with hydrogen silicone when under the action of catalyst .also can participate in a variety of other reactions.
