Dow SYLTHERM™ - High Performing Thermal Fluids

Dow SYLTHERM™ Heat Transfer Solutions

Dow has mastered the specialty heat transfer fluid formulation that offers optimal temperature stability and viscosity. These SYLTHERM™ heat transfer chemicals eliminate concern when it comes to factors such as oral toxicity, fluid loss from vapor, and issues surrounding conductivity. In addition, they offer a long and excellent service life and optimal heat transfer performance where it matters most. Though their initial cost is slightly higher, silicone fluids can reduce the long-term operating and maintenance costs because they do not degrade like typical hydrocarbon fluids and, as a result, rarely need to be replaced, reducing associated expenses.

SYLTHERM™ heat transfer fluids are an ideal solution for applications such as oil, gas, and chemical processing. In addition, solar energy manufacturing and pharmaceutical reaction applications can greatly benefit from SYLTHERM™ heat transfer thermal fluids.
