1,3,5,7-Tetramethylcyclotetrasiloxane(D4H)

Silor^TMD4H ,1,3,5,7-Tetramethylcyclotetrasiloxne is a kind of active siloxane with Si-H bond, which can make addition reaction with unsaturate olefin. Comparing with line chain polymethylhydrosiloxane, D4H has better properties including lower impurity, higher purity, more fixed chain, and better design for modifided molecular. D4H is used for preparation of methylhydrosiloxane which needs certain hydrogen or linker chains, and polysiloxane which needs modified functional group.
