Application
1. Hydride Terminated Polydimethylsiloxane is usually used as a silicone end-capping agent.
2. Due to Hydride Terminated Polydimethylsiloxane containing reactive Si-H groups in the molecular structure, it can be used in the synthesis of copolymer macromolecules by hydrosilylation. The synthesis of copolymer macromolecules can be made into a series of reactive silicone oil.
3. Hydride Terminated Polydimethylsiloxane is usually used to produce textile softener, block silicone oil, surface-active agents.
4. As a chain extender for adding liquid silicone rubber, adding a crosslinking agent for forming a hot vulcanized silicone rubber;
5. As a waterproofing agent and softener for natural and synthetic fabrics;
6. As the special silicone surfactant;
7. Hydride Terminated Polydimethylsiloxane can be used in the manufacture of a variety of end group reactive linear modified silicone oil.
8. As the key intermediates of block copolymerization reaction.
9. As a modification of the reaction, such as plastic resin.
