Product Description

                           Siwin-VF21A  Vinyl Terminated polydimethylsiloxane
 

Description

Siwin-VF21A is vinyl terminated in two ends of polydimethylsiloxane, the molecular is 300 - 300000 (synthesis different molecular in customers requirements). Because of formula structure, molercular is bigger, vinyl content is smaller. Except for with PDMS normal benefits, it also has unique functions:
1.Two ends of vinyl group with strong active, it can addition reaction with hydrogen silicone oil
under catalyst.
2.Comparing with PDMS, Siwin-VF21A has more better compatible with organic solvents, it more easy to use together with other organic materials.

 

Application

1.As the additive materials in silicone rubber to improve the strength and hardness
2.As the key raw materials in molding liquid silicone rubber
3.It can react with many organic raw materials, such as, PU, Acrylic to make more functional materials.
