Advantages
♦ Narrow fraction, high initial distillation point
♦ Good thermal anti-oxidation stability, long service life
♦ Less evaporation, high flash point
♦ High specific thermal capacity, good thermal transmission capacity
♦ Excellent low temperature flow performance
♦ Good compatibility with material of the system, no corrosion
Performance
Meet the following performance specification:
♦ SH/T 0677-1999
Applications
♦ Suitable for closed heat transmission system of forced circulation or unforced circulation, suitable for drying, heating processes, such as timber processing, textile finishing, food processing, chemical industries, etc.
