Product introduction of XJY-707 Hydride Terminated PolyDimethylsiloxanes


Structural formula:
XJY-707 Hydride Terminated PolyDimethylsiloxanes
CAS NO. :70900-21-9
Molecular weight: 450-500
Appearance: Colorless clear liquid


Features of XJY-707 Hydride Terminated PolyDimethylsiloxanes


XJY - 707 polydimethylsiloxane PDMS is 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.
