Application

SiSiB® PC9240 may be used as synthetic equivalents for the reactive intermediate dimethylsilanone.

SiSiB® PC9240 may be used to synthesize silicone oil, which may has lower freezing point and less surface tension, it is slightly affected by temperature.

SiSiB® PC9240 may be used as an effective trapping reagent for a variety of short-lived intermediates, including silanones and silyenes.

SiSiB® PC9240 D3 hexamethylcyclotrisiloxane has many unique characteristics than SiSiB® PC9100 (D4).

SiSiB® PC9240 may be used to synthesize silicon rubber, which may has better elasticity, better abrasive resistance, and better corrosive resistance.

The reaction of SiSiB® PC9240 is more active, can be easily and quickly polymerized under lower temperature and simple catalysts.

SiSiB® PC9240 may be used to synthesize many kinds of organic silicone products, which have better stability, better insulation properties and better water resistance.
