Vinyl silicone oil
Vinyl silicone oil include:
LV-A: Vinyl terminated methyl silicone
LV-B: Vinyl terminated methyl vinyl silicone oil
LV-C: Methyl blocking polymethyl vinyl silicone oil
Product Information:
LV-A: Vinyl terminated methyl silicone
This product is the end vinyl polydimethylsiloxane. It’s an excellent and lively intermediate material. The product has the methyl silicone oil’s common performance (such as : smoothness, limpness, bright, temperature and durability etc), also have below features:
1. 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.
2. Has better intermiscibility with organic material compare to methyl silicone oil, easier compatibility with other organic materials.
3. For containing lively double bond, easy to have reaction with organic material such as polyurethane, acrylic acid etc.
