Novec(tm) HFEs
3M™ Novec™ HFEs are a family of low-Global Warming fluids (segregated hydrofluoroethers) designed to replace CFCs and HCFCs. Novec HFEs offer balance performance with favorable environmental and H&S properties.
Novec fluids offer:
- Low toxicity
- Zero Ozone Depletion Potential (ODP)
- Low Global Warming Potential (GWP)
- Thermal and Chemical stability
- Hydrolytic stability
- Non-corrosive
- Excellent dielectric properties
- Low viscosity and surface tension
- Wide range of boiling points
- Good materials compatibility
- Non-flammable
Applications:
- Particulate cleaning
- Co-solvent rinse agent for precision cleaning
- Carrier Solvents for Fingerprint Formulations
- Deposition Solvents
- Heat Transfer Fluids
