An Alkylated Aromatic Heat Transfer Fluid Designed for Use as an Alternative for Hot Oils in Liquid Phase Systems Up To 620°F (327°C).
Product Overview

DOWTHERM™ MX is a high-performance thermal fluid based on a mixture of alkylated aromatics for high temperature, non-pressurized systems up to 620°F (327 °C).

DOWTHERM™ MX is designed as an alternative for hot oils in liquid phase systems.

DOWTHERM™ MX exhibits a high flash point and superior thermal stability when compared to traditional hot oils.
