Fluorinert™（Fluorine-type inert liquid）
A colorless, clear, fluorine-type inert liquid
Fluorinert™（Fluorine-type inert liquid） is a colorless, clear, fluorine-type inert liquid with high stability.In addition, because it is inert and has little effect on constituent materials, refrigerant applications and electronic components, etc., can be tested in a directly-immersed state.
- Has superior electrical insulation properties and thermal conductivity.
- Does not dissolve in various solvents, whether at high or low temperature.
- Completely inert, and does not eat into metals, plastics, rubber, etc.
- Has very low surface tension (12 to 18 dynes/cm 25°C) and superior permeability.
- It is safe, being non-flammable, non-toxic, and odorless.
