A diaryl alkyl heat transfer fluid that is intended for use in applications that require liquid phase heat transfer
Unlike other low pressure fluids - including partially hydrogenated terphenyls and dibenzyl toluene fluids, DOWTHERM™ RP fluid degrades primarily to low molecular weight products. DOWTHERM™ RP has a Maximum bulk temperature of 350 °C (660 °F) and a maximum film temperature of 375 °C (710 °F).
Used in production of PET resin, PET film, phenol, polycarbonate, polystyrene, refineries, LNG, offshore platforms
Best thermal stability of any liquid phase fluid
Does not form tar or high boiling degradation products
Liquid phase fluid used in pressure-less or low-pressure systems
