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.
