Suitable viscosity: low viscosity heat transfer medium is conducive to achieve high heat transfer coefficient in turbulent state, and has good pumpability at low temperature, so that the pumping device is easy to start; Higher specific heat and thermal conductivity, in order to get higher thermal efficiency.
Excellent high and low temperature performance and excellent viscostatic temperature characteristics: viscosity changes with temperature is small, low temperature fluidity is good, flash point and spontaneous combustion point is high, high thermal decomposition temperature, can meet the maximum use temperature of 350℃ use requirements, with fire resistance, allow the maximum film temperature 375℃;
Excellent chemical stability and thermal stability, with very low volatility, good thermal oxidation stability, long service life, service life as long as seven to twelve years; Good
radiation resistance and adaptability to rubber seals.
Suitable for heating or heat removal systems in various high-tem perature heating production processes such as light industry and chemical industry, petrochemical industry, oils and fats, plastic rubber, leather industry, textile printing and dyeing, chemical
fiber, coating paint, car aircraft, wood processing, forest product industry, paper printing, building materials, cement, carbon in dustry,highway transportation, municipal highway construction asphalt heating,air conditioning,pharmaceutical industry, metal
processing,electrical appliances, food industry, grain and oil foods, etc., liquid-phase closed heat conduction system not higher than 350°C.
