Fluoride Offgassing in Fluoropolymer Insulations
This SAE Aerospace Recommended Practice (ARP) shall be limited to information about corrosion caused by fluoride offgassing of fluoropolymer-based wire insulation. It reviews published reports of corrosion caused by this phenomenon, describes scenarios where this may be a concern, mitigation options, and references a test method which can be used to evaluate wire insulations where needed.
This report provides information to the user community on the potential of fluoride offgassing from fluoropolymer wire insulation and recommendations to protect against potential effects. Although there have been some published advisories related to this subject, no publication existed prior to this ARP which pulls together current knowledge for communication to industry OEMs and end-users.
