Hydrogen Terminated Silicone Oil: Guide

Hydroxy Terminated Silicone Oil (CAS 70900-21-9), also known as Hydroxy Terminated Polydimethylsiloxane, is produced by reacting tetramethyldisiloxane with octamethylcyclotetrasiloxane (D4) using sulfuric acid or other acidic catalysts. The molecular weight and hydrogen content vary based on the capping agent to D4 ratio. This silicone oil contains active Si-H bonds at both ends of the molecule, giving it high reactivity. It is a non-toxic, odorless, transparent liquid commonly used as a key reactive intermediate in silicone-based applications.
