Hazard InformationBack Directory
[Uses]

HYDRIDE TERMINATED POLYDIMETHYLSILOXANE is the hydride terminated form of polydimethylsiloxane, which belongs to a group of polymeric organosilicon compounds. It can be used as a common surfactant and an antifoaming agent. It can also be applied as the active silicone fluid in automotive viscous limited slip differentials and couplings. Moreover, it is commonly used as a stamp resin in the field of soft lithography. Finally, it can also be supplemented to the over-the-counter drugs as an antifoaming agent and carminative. For example, it is seen in many skin care and beauty products to prevent water and moisture loss in the skin through forming a hydrating barrier.
[Uses]

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.
