Update:2022-04-22 00:00
Summary:

1,3,5,7-Tetramethylcyclotetrasiloxane is a reactive siloxane containing silicon-hydrogen bonds that can undergo addition reactions with unsaturated olefins. It can be used to prepare polymethylhydrogensiloxane and functional group-modified polysiloxane with specific hydrogen content and required a number of segments; it can be used to synthesize room temperature vulcanized silicone rubber and special crosslinking of addition type liquid silicone rubber. agent; synthetic side-chain polysilicon Oxane liquid crystal polymer and various functional side chain modified silicone oil. High purity can also be used in the electronics industry as a precursor for plasma vapor deposition to form silicon dioxide, and silicon carbide insulating films. It is used to synthesize organic silicon intermediates and polymer compounds to provide active cross-linking points and is one of the indispensable raw materials for the preparation of silicone rubber.

Compared with linear polymethylhydrogensiloxane, tetramethyl cyclo tetrasiloxane has fewer impurities, high purity, fixed chain links, and is easy to modify the design of molecules. It can be used to prepare various specific hydrogen content and required Methyl hydrogen siloxane and modified siloxane with the number of segments. Such as: used to prepare high molecular weight hydrogen-containing silicone oil; cross-linking agent for the preparation of room temperature vulcanized silicone rubber and addition type liquid silicone rubber;

Sidechain polysiloxane liquid crystal polymer, and various high-quality side-chain modified silicone oil. Such as long-chain alkyl silicone oil; polyether silicone oil; epoxy silicone oil; carboxyl silicone oil; amino silicone oil, etc.Tetramethylcyclotetrasiloxane is also an excellent impregnating agent for optoelectronic materials.
