3M Novec 7000 Engineered Fluid is a nonflammable, low global warming potential heat transfer fluid capable of reaching temperatures as low as -120°C. Chemically known as 1-methoxyheptafluoropropane (C₃F₇OCH₃), this ultra-low boiling point fluid (34°C) offers exceptional performance in semiconductor manufacturing equipment cooling, direct expansion refrigeration, and extreme low temperature heat transfer applications. With zero ozone depletion potential, a GWP of 370, and an exceptionally low viscosity of 0.32 cSt at 25°C, Novec 7000 delivers reliable thermal management in ion implanters, dry etchers, CVD/PVD tools, supercomputers, and sensitive military electronics.
Novec 7000 maintains excellent flow characteristics even at extreme low temperatures — viscosity of 2.0 cSt at -80°C and 17 cSt at -120°C — ensuring consistent performance in demanding cryogenic applications. Its excellent dielectric properties (dielectric constant 7.4, dielectric strength -40 kV, volume resistivity 10⁸ ohm-cm) provide reliable electrical insulation in high-voltage environments. Nonflammable, non-corrosive, and thermally stable, Novec 7000 ensures safe operation in electronics cooling, industrial freeze dryers, chemical reactors, fuel cells, and electronics reliability testing.
