No Chemical Attack…. So You’re Sure It’s Pure
Foods don’t react with DuPont Teflon, so there are no chemical interactions or corrosion to compromise taste or create contamination. The near-universal chemical resistance of Teflon is a key reason for its broad use in fluid-handling components and vessels used in the chemical processing and semiconductor manufacturing industries.
Telfon adds essentially nothing to foods and takes nothing away. With extremely low extractables and reactivity plus high purity, Teflon meets a wide range of regulatory requirements. Unlike some other polymers, Teflon contains no additives to compromise the flavor or contaminate products.
And Teflon doesn’t absorb dilute solutions of benzoic acid and other common food preservatives, which can be a problem with handling preservatives with silicone rubber and PVC tubing.
Grades of Teflon PTFE granular resins and fine powder resins and Teflon FEP may be used in food contact applications in compliance with the U.S. Federal Food and Drug Administration’s (FDA) Regulation 21 CFR 177.1550. Teflon PFA 440 HP and 450 HP also comply. The U.S. Department of Agriculture accepts grades of Teflon that comply with this FDA regulation as components of materials in direct contact with meat or poultry food products prepared under Federal inspection.
