LF-OHPM Phenyl Methyl Hydroxy Silicone Oil
CAS NO.: 80801-30-5
Silfluo LF-OHPM is a silanol-terminated polymethylphenylsiloxane (CAS 80801-30-5) with methylphenylsiloxane repeat units and reactive Si–OH end groups on both chain termini.
The mixed methyl-phenyl substitution on silicon places LF-OHPM between standard PDMS (LF-OHP, methyl only) and fully diphenyl-substituted LF-OHP2 in terms of refractive index (1.430–1.500), thermal stability, and low-temperature flexibility — the methyl groups retain chain flexibility that the all-phenyl LF-OHP2 sacrifices, while the phenyl groups raise RI, thermal stability, and radiation resistance above standard PDMS.
Viscosity range (500–20,000 mPa·s) spans medium to high molecular weight, allowing selection based on required compound processing viscosity and target cured elastomer mechanical properties.
