Polydimethylsiloxane hydride terminated is soluble in many organic solvents, such as aromatic hydrocarbon and petroleum hydrocarbons, and so on. it is a kind of widely used organic silicon intermediates, and can be used as organic silicon blocking agent usually. Due to containing reactive Si-H groups in the molecular structure, it can be used in the synthesis of copolymer macromolecule by hydrosilylation. The synthesis of copolymer macromolecule can be made into a series of reactive silicone oil.

??

1. Hydride Terminated Polydimethylsiloxane Can be Used in manufacture of a variety of end group reactive linear modified silicone oil, modification of the reaction, such as plastic resin.
2. The key intermediates of block copolymerization reaction.
3. can be used as chain extension agent for addition liquid silicone rubberm, crosslinking agent for addition liquid silicone rubber.
