LS-614 Hexaphenyldisiloxane
CAS NO. 1829-40-9
Silfluo LS-614 is Hexaphenyldisiloxane, a solid-state phenylsilicone intermediate.
The molecule contains six phenyl groups on a single Si–O–Si disiloxane backbone, with triphenylsilyl groups at each end.
The high phenyl density raises refractive index and thermal stability of derived siloxane networks relative to lower-phenyl-content analogs.
Used as end-capping agent and structural modifier in phenyl silicone resin synthesis, high-RI optical encapsulant formulation, and specialty silicone fluid preparation.
