Hydride Terminated Polydimethylsiloxane

Hydride terminated polydimethylsiloxane contains highly active Si-H bonds and is the basic raw material for the synthesis of SRS modified silicone oil, such as polyether-modified silicone oil and alkyl-modified silicone oil. It is also a cross-linking agent for addition-type silicone rubber.

USES AND APPLICATIONHydride terminated polydimethylsiloxane is not only the basic raw material for synthesizing SRS modified silicone oil such as polyether-modified silicone oil, alkyl-modified silicone oil,but also a kind of cross-linking agent for addition-type silicone rubber.It is the basic intermediate raw material for hydrosilylation reaction and is often used to manufacture various end-group reactive linear modified silicone oils. It is a key intermediate for block copolymerization reaction. The product can be as a chain extender for addition type liquid silicone rubber and cross-linking agent for addition type thermally vulcanized silicone rubber, which can improve the product's elongation at break, increase toughness, and reduce hardness.The starting material of organic polymer modified materials, often used in modification reactions of plastic resins, etc.

 

SAFETY

Before handling, read the Material Safety Data Sheet and container label for safe use, physical and health hazard information.

 

STORAGE AND SHELF LIFE
