RFCTHERM-400
CAS No: 8004-13-5
Product Description
RFCTHERM-400 is a eutectic mixture of 73.5% diphenyl oxide (DPO) and 26.5% biphenyl, it is a synthetic heat transfer fluid designed to meet the demanding requirements of vapor phase systems from 257° C to 400° C or liquid phase systems from 12° C to 400° C, It combines exceptional thermal stability and low viscosity for efficient, dependable, uniform performance in a wide optimum use range, RFCTHERM-400 has the highest thermal stability of all organic heat transfer fluids. It is miscible and interchangeable (for top-up or design purposes) with other similarly constituted diphenyl-oxide (DPO)/biphenyl fluids, such as: Therminol-vp-1, Dowtherm-A, Therm-S 300 and Diphy1.
