APPLICATION
Biphenylbiphenylether mixture thermal oil is a high-temperature gas/liquid dual-purpose high-temperature synthetic organic heat carrier with high thermal stability. It is an eutectic mixture composed of 26.5% biphenylbiphenylether and 73.5% biphenylether.It can be used as a liquid phase thermal oil, or it can be used as a gas phase thermal oil in the temperature range of 257℃-400℃ using its evaporation-condensation characteristics. It is widely used in the CSP solar thermal power generation industry and the chemical fiber chemical industry.
