Applications

1.Serves as the basic intermediate raw material for hydrosilylation reactions, and is commonly used in the preparation of various end-reactive linear modified silicone oils.

2.Acts as a key intermediate for block copolymerization reactions.

3.Can be used as a chain extender for addition-type liquid silicone rubber and a crosslinking agent for addition-type heat-curable silicone rubber, which can improve the elongation at break of products, enhance toughness and reduce hardness.

4.Functions as the starting raw material for organic polymer modification, and is widely applied in the modification reactions of materials such as plastics and resins.
