Features:
The product is refined by advanced technology and has passed the GB23971-2009 national type test. L-QC320 synthetic heat transfer oil has the characteristics of low viscosity, high density and less impurities. The oxidation resistance is up to 400 minutes, and the annual coking rate is only one in ten thousand. The thermal stability is superior to the mineral heat transfer oil, and the fluidity is strong and the energy consumption is low. The maximum temperature can reach 320 °C. Widely used in waterproof materials, textiles, wood, chemicals, carbon, asphalt mixing plants and other industries.
