PTFE and PFOA are two different substances that are often associated with non-stick cookware, such as Teflon (a trademark owned by Dupont). Here’s a brief overview of each:
PTFE (Polytetrafluoroethylene):PTFE is a synthetic fluoropolymer with remarkable non-stick properties.It is commonly used in non-stick cookware (smoking, baking, toasting) and garment graphics (heat press contact sheets, pillows, platen wraps).PTFE is a solid material that is very resistant to heat and chemicals, which makes it suitable for use in cookware.It is generally considered safe for cooking because it is inert and does not react with food at typical cooking temperatures.However, PTFE can release toxic fumes if it is heated to extremely high temperatures (above 500°F or 260°C), which can be harmful to humans and pets. This is why it’s important not to overheat Teflon-coated cookware.PFOA (Perfluorooctanoic Acid):
PFOA is a synthetic chemical compound that was historically used in the production of PTFE, including Teflon products.It is not present in the final PTFE-coated products but can be used in the manufacturing process.PFOA has been a cause for concern due to its potential environmental and health hazards. It is a persistent organic pollutant that can accumulate in the environment and in the human body.Long-term exposure to PFOA has been linked to health problems, including potential carcinogenic effects and developmental issues.
