Description
Other Name: Vinyl terminated polydimethylsiloxane, Vinyl Functional Silicone Fluid, Vinyl Silicone Fluid
CAS No: 68083-19-2
Chemical Structure:
As regard of Vinyl Silicone Oil TPD-Vi901, the higher the molecular weight, the lower the vinyl content, on the contrary, the smaller the molecular weight, the higher the vinyl content. TPD-Vi901 is an excellent and active intermediate.
Features
- The vinyl groups at both ends make it has a strong reactivity
- Better compatibility with organic materials than dimethyl silicone oil
