Product Description

Production

 

 

 

Silway D4H
 

Silway D4H is 1,3,5,7-Tetramethylcyclotetrasiloxane, a kind of active siloxane with Si-H bond, which can make addition reaction with unsaturate olefin. 
 

Comparing with line chain polymethylhydrosiloxane, Silway D4H has fewer impurity, higher purity, more fixed chain, and easy to modify molecular design. This product is the production of commercial grade hydrogen silicone and modified silicone oil, silicone surfactants, liquid silicone rubber's cross-linking agent and adhesive's important intermediate.
