Application
Siwin-D4H 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 various specific hydrogen contents and required number of chain links;
Tetramethylcyclotetrasiloxane can be used to synthesize special cross-linking of room temperature vulcanized silicone rubber and addition liquid silicone rubber. agent; synthesizes side chain polysiloxane liquid crystal polymers and various functional side chain modified silicone oils.
High purity Tetramethylcyclotetrasiloxane 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 silicone intermediates and polymer compounds to provide active cross-linking points.
Tetramethylcyclotetrasiloxane is one of the indispensable raw materials for preparing silicone rubber.
Tetramethylcyclotetrasiloxane can be used to prepare high molecular weight hydrogen-containing silicone oil;
Tetramethylcyclotetrasiloxane as cross-linking agent for preparing room temperature vulcanized silicone rubber and addition liquid silicone rubber;
Tetramethylcyclotetrasiloxane is used to synthesize side chain polysiloxane liquid crystal polymers, and various high-quality side chain modified silicone oils . Such as: long chain alkyl silicone oil; polyether silicone oil; epoxy silicone oil; carboxyl silicone oil; amino silicone oil, etc.
