Phenyl Silanes

SiSiB is worldwide leading supplier of organosilanes for over 30 years. SiSiB phenyl silanes are used to synthesize phenyl silicone oil, phenyl silicone resin and phenyl silicone rubber. SiSiB phenyl silanes are also be used for resin modification to provide high and low temperature resistance, radiation resistance and aging resistance. SiSiB phenyl silanes are used as silylation reagent.

The hydrosilylation reaction is a dominant curing method for the light-emitting diode (led) silicone encapsulant, which requires characteristics of high transparency, high refractive index, and thermal stability against the led junction temperature. Phenyl silanes by SiSiB, a reliable silicone supplier, may be used as a precursor in the synthesis of linear vinyl oligosiloxane resins which can be used in the production of thermally resistant light emitting diode (LED) encapsulant.

In addition, SiSiB® PC8131 (Phenyltrimethoxysilane) contains phenyl groups, exhibits excellent thermal stability, is particularly suitable for polymers processed at high temperatures, and brings flexibility to sol-gel coating systems. SiSiB® PC8131 can be used for surface hydrophobic treatment of inorganic fillers such as wollastonite and aluminum trihydroxide, thereby increasing their dispersibility in mineral-filled polymers.

SiSiB® PC8221 (Diphenyldihydroxysilane) can be used as a stereo-regulator for Ziegler-Natta-catalysts to increase the isotactic index in polypropylene. (B donor)

SiSiB® PC8228 (Diphenyldihydroxysilane, also known as Diphenylsilanediol) can be used to synthesize octaphenylcyclotetrasiloxane. SiSiB® PC8228 can also be used as anti-structuring (crepe hardening) additive for filled silicone rubbers to improve processing performance.

SiSiB® PC8318 (Triphenylsilanol, CAS No. 791-31-1) can be used as an end-capping agent for linear polysiloxanes, a molecular weight regulator for polymerization reactions, and a protective agent for organic reactions.

SiSiB® PC8801 (1,1,5,5-tetramethyl-3,3-diphenyltrisiloxane, CAS No. 17875-55-7) can be used to synthesize pharmaceutical intermediates. SiSiB® PC8801 can also be used as crosslinkers for liquid silicone rubber, phenyl silicone rubber and phenyl resin.
