XJY-705 1,3,5,7-Tetramethylcyclotetrasiloxane

1. PRODUCT FEATURES of XJY-705 1,3,5,7-Tetramethylcyclotetrasiloxane

Chemical Name: 1,3,5,7-tetramethylcyclotetrasiloxane
Structural Formula:
XJY-703 Bis(Trimethylsiloxy)Methylsilane

XJY - 705 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 usually be used as organic silicon blocking agent. Due to containing reactive Si-H groups in the molecular structure, XJY-706 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.
