PTFE, PFA and FEP are all fluoropolymers that create a non-stick surface on the food-contact surface of cookware and bakeware products. Although inert solids, PTFE, PFA and FEP are classified as PFAS substances and must be disclosed. Given that PFAS is a broad categorization that includes thousands of fluorochemicals, we recommend visiting the below source to learn more about the different types of PFAS substances.
The California Safer Food Packaging and Cookware Act requires manufacturers to disclose the presence of certain chemicals in their products. Chemicals required to be disclosed are listed on the California Department of Toxic Substances (DTSC) Candidate Chemical list. DTSC identified PFASs based on the CECBP Priority Chemicals Authoritative List found at https://biomonitoring.ca.gov/chemicals/priority-chemicals. Further information about PFASs can be found at the DTSC website.
If you have any questions about whether PFASs are contained in any specific National Presto product, please contact customer service at 1-800-877-0441.
