Application Areas
Aerospace, biomedicine, petrochemical superconducting heat transfer, vacuum distillation, ultra-low temperature cryogenic systems, etc.
Temperature-dependent broadband physical properties
Non-flammable Non-corrosive Low freezing point Low-temperature fluidity
Temperature Range
-110℃—45℃
Precautions
Ensure the system is clean and free of moisture before injection; for large-scale systems, use an N₂-pressurized closed expansion cycle whenever possible.
On October 27, 2017, the International Agency for Research on Cancer of the World Health Organization classified dichloromethane as a Group 2A carcinogen. Among occupational diseases caused by repeated exposure, it is explicitly stated that short-term exposure leads to specific target organ toxicity.
2. Temperature range resistance ≥ 100 MΩ/kV·m; dielectric constant: ≈2
