Clearco - Model DPDM-400 - Diphenyl-Dimethyl Silicone Fluid
From Silicone Fluids
Product Description: PM‐125 Silicone Fluid is a clear, colorless and odorless Diphenyl‐Dimethylsiloxane Silicone Oil with a viscosity of 400cSt @ 25°C. It replaces methyl groups found in conventional PDMS Silicone oils with a high percentage of Diphenyl groups. In doing so, thermal stability and resistance to oxidation are significantly increased. DPDM‐400 provides long term stability at 250°C (open to air) and 300°C (closed to air). The fluid is further characterized by its high flash point, high dielectric strength, stability at extreme pressures, good heat capacity values, excellent lubricity and inertness to virtually all substrates.

As a calibration fluid, DPDM‐400 Silicone Fluid is widely used in Flow Control, Temperature Control and Motion Control technologies. Again, its advantage over conventional oils is that it will not break down at high temperatures and it will not coagulate at high pressures. It is widely used for instruments, gauges, sensors, meters and devices that are subject to extreme temperatures and high pressures.
DPDM‐400 Silicone Fluid has a higher RI value (1.505) than conventional PDMS silicone. It an excellent RI index matching fluid and optical fluid for use in sensor /imaging / LED and Photonics technologies that require a higher RI value than conventional fluids.
