Products Description: Clearco Diphenyl-Dimethylsiloxane fluids are phenyl-based silicones that are formulated for applications where Dimethyl silicones will not remain stable. These fluids are described as aromatic siloxanes due to the presence of phenyl groups. High phenyl content fluids (DPDM-200) are utilized as heat exchange fluids, dielectric coolants, and base oils for high temperature fluids. Low phenyl content fluids (DPDM-100) can be utilized for similar applications, but can also be used at lower temperatures than higher phenyl content fluids. Applications for Low phenyl content fluids include wide temperature range baths, low temperature baths, and fluids for sensitive timing and calibration devices.

Phenyl-based silicones replace methyl groups with phenyl groups. With the introduction of phenyl groups into the polysiloxane, oxidation resistance, thermal stability and shear resistance are enhanced. At elevated temperatures, phenyl-based silicones are more stable and resistant to thermal and oxidizing attack. In addition, refractive index is increased, making them suitable fluids where the RI matches that of optical fibers, allowing for invisible connections and transparent blends.
