Where the World Gathers to Celebrate Every Day



National Teflon Day April 6


National Teflon Day is observed each year on April 6.  It honors the accidental invention of Teflon on April 6, 1938, by Dr. Roy Plunkett.

While working in the Chemours Jackson New Jersey lab that April day, Plunkett, along with his assistant, accidentally discovered polytetrafluoroethylene.  Chemours registered the Teflon trademark in 1945. Dr. Plunkett was added to the Inventors’ Hall of Fame in 1985.

If Plunket invented Teflon, which was trademarked in 1945, then Marion A. Trozzolo brought from the laboratory into the kitchen.  The Kansas City, Missouri professor had been using the substance to coat his scientific utensils.  He later founded Laboratory Plasticware Fabricators.

In 1961, he marketed the first US-made Teflon coated frying pan, “The Happy Pan.”

Kansas City, Missouri resident Marion A. Trozzolo had been using the substance on scientific utensils, marketed the first US-made Teflon coated frying pan, “The Happy Pan,” in 1961.

Teflon can be found everywhere and in surprising places, too.  Besides coating metals for cooking, it is also used to protect fabrics, to reduce friction in the aerospace industry and helps to increase production and reduce contamination in pharmaceuticals.


Bring the Teflon cookware and use #NationalTeflonDay to post on social media.
