About Food Contact Testing of Perfluorocarbon Resins
Perfluorocarbon resins are used in a wide variety of repeated-use non-stick coatings that contact food. The FDA requires that perfluorocarbon resins intended for use in food contact applications must meet certain requirements for identity and use as a coating. This method covers 21 CFR 177.1550.

Approach
1. Samples must be identified by Fourier transform infrared spectroscopy (FTIR) analysis and compared with the list of approved materials in 32 CFR 177.1550.
2. Extraction of identified perfluorocarbon resins occurs at reflux temperatures for 2 hours in each of distilled water, 8% ethanol, and n-Heptane.
3. Total extractives are not to exceed 3.1 milligrams per square decimeter (0.2 mg/sq in).
