Application

Poly(dimethylsiloxane), hydride terminated, is a versatile form of polydimethylsiloxane that functions as a key polymeric organosilicon compound. Its primary purposes include serving as a common surfactant and an antifoaming agent. In the automotive industry, it plays a critical role as the active silicone fluid in viscous limited-slip differentials and couplings. In the field of soft lithography, it is frequently utilized as a stamp resin. Additionally, it finds application in over-the-counter drugs as an antifoaming agent and carminative, and is often included in skincare and beauty products to create a hydrating barrier that prevents moisture loss. Its solubility in various organic solvents, including aromatic and petroleum hydrocarbons, makes it a widely-used organosilicon intermediate, typically functioning as an organic silicon blocking agent. The reactive Si-H groups in its molecular structure allow it to participate in hydrosilylation, facilitating the synthesis of copolymer macromolecules, which can be developed into various reactive silicone oils.
