Compared to the same viscosity of dimethyl silicone fluid, phenyl methyl
silicone fluid has higher coefficient of viscosity-temperature, lower freezing
point and higher flash point.
The most commonly used high temperature silicone fluids are phenyl silicone
fluids. When the phenyl group in the polysiloxane replaces the methyl group,
oxidation resistance, thermal stability, and shear resistance are all improved.
The phenyl group is usually introduced by a phenylmethylsiloxane or a
diphenylsiloxane.
phenyl methyl silicone oil with high phenyl content by SiSiB, a relaible
silicone producer, is used as heat exchange fluid, dielectric coolants, base
silicone diffusion pump oil for high temperature fluid and chromatographic
stationary phases. The higher the phenyl content, the better the high
temperature thermal stability. Refractive index also increases with phenyl
concentrations.
Silicone fluids with low phenyl content are used at lower temperatures and are
usually used as lubricants for key equipment. SiSiB provides a wide range of
phenyl silicone fluids with different viscosities.
Low-viscosity phenyl fluids, SiSiB® PF8704 diffusion pump fluid, CAS No. 3982-
82-9, 1,1,5,5-Tetraphenyl-1,3,3,5-tetramethyltrisiloxane , , is designed for high
vacuum pump; SiSiB® PF8705 diffusion pump fluids, CAS No.3390-61-2, 1,1,3,5,5-
Pentaphenyl trimethyltrisiloxane, is designed for ultra-high and ultra-clean
vacuum.
SiSiB® PC19816 (Phenyl Trimethicone) has good compatibility which can improve
the performance of a variety of cosmetic formulations. It is often used in
cosmetics and beauty products functioning as an anti-foaming agent, hair
conditioning agent and skin-conditioning agent.

Phenyl Silicone Fluids Recommendations

SiSiB® PC19816
SiSiB® PC19816 is a phenyl-modified polymethylphenylsiloxane which is co-
soluble with ethanol and mineral oils. It is used in the formulations to
improve the functions of cosmetic ingredients and used as a waterproof additive
to reduce the viscosity of the formulation so that many effects can be
achieved. INCI Name: Phenyl methicone.

SiSiB® PC19826
SiSiB® PC19826 is a phenyl-modified polymethylphenylsiloxane which is co-
soluble with ethanol and mineral oils. It is used in the formulations to
improve the functions of cosmetic ingredients and used as a waterproof additive
to reduce the viscosity of the formulation so that many effects can be
achieved. INCI Name: Phenyl Trimethicone.

SiSiB® PF8250
SiSiB® PF8250 is polyphenylmethyldimethylsiloxane, which is similar to Dow's
DC-510, Shin-Etsu's KF-50. It has low viscosity, low freezing point, heat
resistance, relatively high flash point, expansion coefficient, superior
electrical performance (anti-corona, the average high pressure).

SiSiB® PF8255
SiSiB® PF8255 is polyphenylmethyldimethylsiloxane, which is similar to Dow's
DC-550, Shin-Etsu's KF-54. It has a good miscibility with other organic resins,
suitable for skin protection and soften, and is used for high-temperature heat
carrier or as insulation oil, high-temperature heating oil bath and base oil.

SiSiB® PF8704
Silicone Diffusion Pump Fluid SiSiB® PF8704 is a single component fluid
designed for high vacuum applications, which is equal to Dow's DC-704, Shin-
Etsu's HIVACF-4. Its low vapor pressure and thermal stability make it popular
in processes such as vacuum coating, metallurgical work.

SiSiB® PF8705
Silicone Diffusion Pump Fluid SiSiB® PF8705 is a single component fluid
designed for ultrahigh vacuum applications, which is equal to Dow's DC-705,
Shin-Etsu's HIVACF-5. It has the highest phenyl content of all silicone
diffusion pump fluids and the best resistance to radiation.

SiSiB® PF8710
SiSiB® PF8710 is a clear, 100% Polyphenylmethylsiloxane Fluid with a viscosity
of 500cSt. It is characterized by its higher oxidation resistance, high thermal
stability, high dielectric strength, and high damping action.

SiSiB® PF9181
SiSiB® PF9181 is a Phenyl Methyl Cyclic Mixture (Phenylmethylcyclosiloxanes),
which CAS number is 68037-54-7. It is used in phenyl silicone elastomer.
