Ethyl Nonafluorobutyl Ether (PFE-20) is a high-performance replacement / alternative for 3M™ Novec™ 7200, offering similar chemistry and physical properties for precision cleaning, vapor degreasing, and heat transfer applications.
PFE-20 is a fluorinated engineered fluid based on HFE-7200 chemistry (ethoxy-nonafluorobutane), designed for advanced industrial cleaning and thermal management applications requiring high reliability and consistent performance.
It delivers comparable characteristics to Novec™ 7200, including a controlled boiling point (~76–77°C), low viscosity, low surface tension, and strong dielectric properties. These features make it highly effective for applications involving fast evaporation, residue-free cleaning, and safe operation with sensitive electronic components.
PFE-20 provides excellent solvency for removing oils, grease, flux residues, and micro-contaminants from precision assemblies. Its low surface tension ensures deep penetration into complex geometries, enabling efficient and uniform cleaning even in tight spaces.
The fluid is widely used in vapor degreasing systems, immersion cleaning, and heat transfer applications across industries such as electronics manufacturing, semiconductor processing, aerospace, medical devices, and precision engineering.
With low toxicity, non-flammability, and zero ozone depletion potential (ODP), PFE-20 meets modern environmental and regulatory requirements. It is suitable for OEM and industrial use where performance consistency and compliance are critical.
