Straight-chain vinyl silicone oil IOTA 273, as an important member in the field of silicone materials, has a chemical name of terminal vinyl polydimethylsiloxane, CAS No. 68083-19-2, and has shown unique performance and value in many industrial applications.
1. Excellent characteristics
Active intermediate: As a good and active intermediate material, it provides a key basis for the synthesis of downstream products.
Inheriting the function of methyl silicone oil: It has all the functions of methyl silicone oil, and at the same time has surpassed it in some performances.
High reactivity: The vinyl reaction activity at both ends is extremely strong, and it can react with hydrogen-containing silicone oil under the action of a catalyst, and can also participate in a variety of other chemical reactions.
Excellent compatibility: The compatibility with organic materials is far superior to methyl silicone oil, making it smoother when it is compatible with other organic materials, and it is easy to achieve performance optimization.
Multi-reactivity: Because it contains active double bonds, it can react with a variety of organic materials such as polyurethane and acrylic acid, which greatly expands its application space.
