Since it comes into direct contact with food and may be ingested, many people worry about whether the coating could peel off during cooking and pose a risk to their health. This raises important concerns about food and health safety.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In the chemical industry, PTFE is used in high-temperature environments. However, if it&#8217;s exposed to temperatures close to its upper limit of 260\u00b0C for extended periods, it may age more quickly, leading to reduced sealing performance and potential safety hazards such as leaks.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In the medical field, PTFE is used in coatings for artificial blood vessels and surgical instruments.

There have been real incidents in the past where PTFE caused harm to human health.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Initially, DuPont in the United States used PFOA to produce Teflon. Soon after, factory workers, nearby animals, and residents began developing cancer, and female workers on the production line experienced stillbirths. Later studies revealed that PFOA is highly toxic and carries significant cancer risks.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_actual_harmful_substance\"><\/span><span style=\"font-weight: 400;\">The actual harmful substance:<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">PFOA, or perfluorooctanoic acid, is a man-made chemical that was widely used in the early stages of PTFE production, often as a &#8216;processing aid&#8217; during manufacturing.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"The_reason_it_is_used_as_a_%E2%80%98processing_aid\"><\/span><span style=\"font-weight: 400;\">The reason it is used as a &#8216;processing aid&#8217;:<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">PTFE&#8217;s monomer is hydrophobic, and the exothermic nature of the polymerization process can potentially lead to an explosion, so water is used to dissipate the heat. PFOA, with its excellent emulsifying properties, helps reduce the surface tension of water, allowing the PTFE monomer to disperse evenly in the water and ensuring the polymerization reaction proceeds smoothly.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">PFOA plays a stabilizing role in the PTFE polymerization process by preventing the polymer particles from clumping together, which ensures that the final PTFE product has good performance.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">PFOA also reduces the adhesion of the polymer to the reactor or other equipment, keeping the equipment clean, lowering maintenance costs, and improving production efficiency.<\/span><\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Why_it_is_harmful\"><\/span><span style=\"font-weight: 400;\">Why it is harmful:<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">PFOA is persistent and bioaccumulative. Once it enters soil or water, it remains there for a long time. If it enters the human body, it accumulates in fat tissue and is difficult to metabolize or excrete, leading to long-term disruption of normal physiological functions.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example, it can affect the endocrine system, potentially causing thyroid dysfunction; the reproductive system, possibly reducing fertility; and has been linked to certain cancers (such as kidney and testicular cancer), high cholesterol, and other health issues.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As a result, most regions around the world have now restricted or banned the production and use of PFOA, and many industries have shifted to safer alternative additives.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Properties_of_PTFE\"><\/span><span style=\"font-weight: 400;\">Properties of PTFE:<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">PTFE is highly chemically inert, with stable chemical properties below 260\u00b0C. In normal use, the cooking temperature of household non-stick pans typically ranges from 180\u00b0C to 220\u00b0C.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">PTFE is also biocompatible, which is why it is used to make artificial blood vessels with a lifespan of around 10 years. It is also used as a coating for surgical instruments. Medical-grade PTFE is strictly purified, free of impurities, and does not cause immune rejection or degradation by bodily fluids.\u3001<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In the industrial field, PTFE is widely used for its corrosion resistance, typically in products such as gaskets and bearings. The substances it comes into contact with are usually strong acids, strong bases, or organic solvents, and PTFE does not react with them due to its properties.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Industrial-grade PTFE is often used as molded products or high-temperature sintered coatings, so it doesn&#8217;t face issues like coating peeling off, as seen in non-stick pans. Additionally, PTFE products experience minimal wear when in friction with mechanical parts, and they do not produce harmful dust.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In electronics, due to PTFE&#8217;s very low dielectric constant, it is used as insulation for cables, effectively preventing current leakage. Thanks to its high and low-temperature resistance, it can also adapt to both cold external environments and the high temperatures generated when cables heat up.<\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Authoritative_certification\"><\/span><span style=\"font-weight: 400;\">Authoritative certification:<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h4><span class=\"ez-toc-section\" id=\"To_completely_dispel_public_concerns_about_the_safety_of_PTFE_international_organizations_and_agencies_such_as_the_FDA_WHO_and_EFSA_have_provided_certifications\"><\/span><span style=\"font-weight: 400;\">To completely dispel public concerns about the safety of PTFE, international organizations and agencies such as the FDA, WHO, and EFSA have provided certifications.<\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The U.S. Food and Drug Administration (FDA) classifies PTFE as an indirect food additive, stating that it is safe under normal usage conditions.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The World Health Organization (WHO) recognizes PTFE as safe for food contact and harmless to human health.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The European Food Safety Authority (EFSA) confirms that swallowing PTFE does not pose a risk to human health.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The International Agency for Research on Cancer (IARC) classifies PTFE as a Group 3 substance, meaning it is &#8216;not classifiable as to its carcinogenicity to humans.&#8217; This indicates that there is currently insufficient evidence to suggest PTFE is carcinogenic to humans.<\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Potential_risks_from_improper_handling\"><\/span><span style=\"font-weight: 400;\">Potential risks from improper handling:<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">If a non-stick pan is overheated, and the temperature exceeds 260\u00b0C, PTFE begins to break down, releasing toxic gases and harmful byproducts such as fluorides.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">If a person inhales a large amount of high-concentration decomposition gases in a short period of time, they may develop &#8216;polymer fume fever,&#8217; which can cause symptoms like chest tightness, coughing, and dizziness.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">When the temperature exceeds 350\u00b0C, the decomposition rate accelerates significantly, and the toxicity increases.<\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Public_concerns\"><\/span><span style=\"font-weight: 400;\">Public concerns:<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Initially, manufacturers used PFOA as a processing aid in the production of PTFE. Later, it was discovered that PFOA is a toxic substance. Although it has been banned now, this has led to continued concern that non-stick cookware with PTFE coatings might pose a risk to human health. However, this worry is unnecessary, as the typical cooking temperatures for frying or scrambling eggs range from 150\u00b0C to 200\u00b0C, and even deep frying doesn\u2019t exceed 230\u00b0C\u2014well below the 260\u00b0C threshold. Furthermore, the U.S. FDA has clearly stated that the amount of fluorides released by PTFE-coated cookware during normal use is far below harmful levels.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Product_Safety_Guidelines\"><\/span><span style=\"font-weight: 400;\">Product Safety Guidelines:<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-14937 aligncenter\" src=\"http:\/\/hansaplas.com\/wp-content\/uploads\/2025\/07\/c1f4507d6f6dd2baea32e4d14f2cd35b.jpeg\" alt=\"\" width=\"349\" height=\"233\" srcset=\"https:\/\/hansaplas.com\/wp-content\/uploads\/2025\/07\/c1f4507d6f6dd2baea32e4d14f2cd35b.jpeg 640w, https:\/\/hansaplas.com\/wp-content\/uploads\/2025\/07\/c1f4507d6f6dd2baea32e4d14f2cd35b-18x12.jpeg 18w\" sizes=\"auto, (max-width: 349px) 100vw, 349px\" \/><\/p>\n<h3><span class=\"ez-toc-section\" id=\"PTFE_non-stick_pan\"><\/span><span style=\"font-weight: 400;\">PTFE non-stick pan<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">First, avoid overheating the non-stick pan to prevent the temperature from exceeding 260\u00b0C.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Add ingredients before the oil starts smoking, as the smoke point is usually below 240\u00b0C.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">When using utensils with the non-stick pan, choose silicone, wood, or nylon spatulas to avoid scratching the coating with hard tools like metal spatulas or steel wool, which could cause the coating to peel off and be accidentally ingested.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">When cleaning, make sure to let the pan cool naturally to avoid cracking the coating due to sudden temperature changes.<\/span><\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"PTFE_sealings\"><\/span><span style=\"font-weight: 400;\">PTFE sealings<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">For household seals, avoid direct contact with high-temperature items like ovens to prevent decomposition from high heat.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">For industrial seals, avoid excessive pulling or friction during installation to prevent the outer layer from wearing down, which could lead to insulation failure or peeling.<\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Ways_for_different_stakeholders_to_mitigate_risks\"><\/span><span style=\"font-weight: 400;\">Ways for different stakeholders to mitigate risks:<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Consumers\"><\/span><span style=\"font-weight: 400;\">Consumers<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">When purchasing PTFE products, make sure to check the label for the maximum temperature tolerance and avoid products without proper labeling or certification.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">If the PTFE coating starts peeling off extensively, it should be replaced promptly.<\/span><\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Manufacturers\"><\/span><span style=\"font-weight: 400;\">Manufacturers<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">When manufacturing PTFE products, high-quality raw materials should be selected and purity tests should be conducted to ensure no impurities are present in the materials.
