PFAS vs PFOA vs PTFE: Understanding the Differences
Author: Hamlet Fort | March 04, 2026 | Time to read: 7 min
If you’ve ever fallen down a cookware rabbit hole, you’ve probably seen these acronyms: PFAS, PFOA, PTFE. They’re often used interchangeably, even though they describe different parts of the same chemical landscape.
But when it comes to choosing cookware for your kitchen and your family, the distinctions matter.
In this article, we’ll break down the chemistry, historical use, and regulatory status of each term, so you can make more informed decisions about your purchases (and not just cookware).
What Are PFAS?
PFAS stands for per- and polyfluoroalkyl substances. It refers to a large class of synthetic chemicals defined by strong carbon–fluorine bonds.
These bonds are among the strongest in organic chemistry, which makes PFAS resistant to heat, grease, and chemical breakdown.
That durability is why PFAS have been used in:
Firefighting foams
Waterproof textiles
Food packaging
Industrial processes
Some nonstick cookware coatings
Because of their environmental persistence, PFAS are sometimes called “forever chemicals.” The term refers to their resistance to degradation. It does not mean all PFAS behave identically in the body.
What Is PFOA? Why Was It Phased Out?
PFOA (perfluorooctanoic acid) is a specific compound within the PFAS family.
Historically, it was used in the manufacturing process of some PTFE coatings. Due to environmental and health concerns, major manufacturers in the United States agreed to phase out PFOA by 2015 under the EPA’s PFOA Stewardship Program.
Today, cookware labeled “PFOA-free” means that the compound is no longer intentionally used in the manufacturing process. However, that label addresses only one specific chemical. It does not necessarily mean the product is free from all PFAS compounds.
Other PFAS-based materials, such as PTFE, may still be present. While regulatory approaches vary globally, PFOA has been eliminated from U.S. cookware manufacturing.
What Is PTFE?
PTFE (polytetrafluoroethylene) is a fluoropolymer used in many traditional nonstick coatings. It is technically classified within the broader PFAS chemical family because of its carbon–fluorine structure.
PTFE behaves differently from smaller PFAS molecules like PFOA. It is a large, stable polymer designed to remain inert under normal cooking conditions, but degradation can occur at sustained temperatures above approximately 500°F. Under normal use, cookware is generally kept below that threshold. Prolonged overheating, especially heating an empty pan, can accelerate breakdown.
Modern PTFE cookware manufactured in the United States is made without PFOA, but PTFE itself remains within the PFAS classification.
Nonstick Alternatives to PFAS-Based Surfaces
Home-cooks today have more options than ever. Each material offers different strengths, depending on how you cook.
Sol-gel ceramic coatings: Mineral-based, typically silica-derived, and made without PFAS.
Titanium (no coating): Pressed titanium cookware can offer durability without synthetic nonstick layers. For example, our NoCo® Titanium collection achieves nonstick performance without coatings.
Enameled cast iron: A glass-like enamel coating fused to cast iron, offering strong heat retention without seasoning requirements.
Stainless steel: Uncoated and versatile. Food release depends on proper preheating and oil use.
Carbon steel and raw cast iron: Naturally seasoned over time and well suited to higher-heat cooking.
Each material involves trade-offs in maintenance, weight, and cooking style. The right choice depends on your routine and preferences.

Final Thoughts
Once you understand how PFAS, PFOA, and PTFE relate to one another, the conversation around nonstick cookware becomes clearer.
At Our Place, we believe cookware should be thoughtfully designed, transparent about materials, and supportive of everyday cooking. That’s why we choose to make ceramic nonstick coated products with Thermakind® technology, made without PFAS, PTFE, or PFOA, and why we also invest in uncoated materials like titanium, carbon steel, and enameled cast iron.
When you understand what’s in your cookware, you can choose what feels right for your home and your table.
