Features ofXJY-707 Hydride Terminated PolyDimethylsiloxanes

XJY - 707polydimethylsiloxane PDMSis soluble in many organic solvents, such as aromatic hydrocarbon and petroleum hydrocarbons, and so on. This product 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, XJY-707 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.
