High Temperature Dielectric Silicone Fluids are Phenyl-class Silicone fluids that are formulated for use in a wide range of applications that require high dielectric strength, high flash points, high thermal stability, resistance to oxidation, long service-life
High Temperature Dielectric Silicone Fluidswill remain stable up to 300°C in a closed system (closed system) and 250°C (open system). They contain no heat-stabilizers or additives. These fluids are hydrophobic, clear, colorless, odorless, and inert to virtually all metals, plastics and rubbers.
High Temperature Dielectric Silicone Fluids have Dielectric Strength of 400 volts/mil
View Dielectric Properties of High Temperature Dielectric Silicone Fluids
High Temperature Dielectric Silicone Fluids have Thermal Conductivity values between 0.00032 to 0.00035 g/cal/cm/sec °C. The Specific Heat values are 0.35 cal/g °C for the DPDM-400 Heat Transfer Fluid. The Specific Heat value for the PM-125 is 1.418 kJ/kg K @ 0°C.
Unlike conventional silicone fluids, the viscosity of the High Temperature Silicone Heat Transfer Fluids will lower very quickly as soon as they are heated. This makes them excellent choices for systems that need to pump the fluid at high temperatures. Under heat, the High Temperature Dielectric Silicone Fluids will easily circulate and provide a consistent temperature.
Applications include: High Temp Dielectric fluids, high temperature dielectric coolants, dielectric fluid for heat transfer systems, calibration bath fluids for high temperature, high temperature silicone fluid for temperature control systems, Downhole (Borehole) Fluid
