HL-400 liquid and gas phase heat transfer oil
Product description
Product composition
The liquid and gas phase heat transfer oil is a eutectic mixture of biphenyl and diphenyl ether copolymerized with a mass ratio of 26.5:73.5.
Performance characteristics
This product is non-corrosive, and has good high temperature resistance and thermal stability, and can be used for a long time in the applicable range of 12-400℃. It has good safety performance, the low saturated steam pressure at high temperature, and it can be used for heating both in the gas phase and in the liquid phase. It can be comparable with the similar products of American Thermino1-vp-1, Dowtherm-A, Japanese Therm-S-300 and German Diphy1 and can be mixed for use.
