Uses Hexamethylcyclotrisiloxane, is the simplest member of a series of cyclic oligodimethylsiloxanes, primarily used as synthetic equivalents for the reactive interme- diate dimethylsilanone. It is one of the main raw materials for silicone products. It is widely used in aviation, military industry, medicine and petrochemicals etc.
Hexamethylcyclotrisiloxane undergoes ring-opening anionic polymerization reactions, suggesting use in polymer synthesis. It is also suggested for the treatment of powders and fillers to render them hydrophobic.
Hexamethylcyclotrisiloxane mainly used for products of methyl vinyl silicone rubber. It`s also the important raw materials for synthesizing other high polymers.
It may be used as an effective trapping reagent for a variety of short-lived intermediates, including silanones and silyenes.
Hexamethylcyclotrisiloxane has many unique characteristics.The reaction of It is more active, can be easily and quickly polymerized under lower temperature and simple catalysts.
may be used to synthesize many kinds of organic silicone products, which have better stability, better insulation properties and better water resistance.
may be used to synthesize silicon rubber, which may has better elasticity, better abrasive resistance, and better corrosive resistance.
may be used to synthesize silicone oil, which may has lower freezing point and less surface tension, it is slightly affected by temperature.
Hexamethylcyclotrisiloxane is flammable. Use and store with all precautions required for Flammable Materials. Care should be exercised in handling GP-685 to prevent contact with skin or eyes. Wear safety glasses with side shields and rubber gloves when handling.
