Thermolon is the mineral-based and patented non-stick coating used by GreenPan on its products. The coating is polytetrafluoroethylene-free, contains no silicone oil and uses no perfluorooctanoic acid during its manufacture.
While cooking over low heat is recommended, the Thermolon coating is heat-resistant up to high temperatures. No toxic fumes are released, and the coating does not blister or peel if a pan coated with Thermolon reaches temperatures up to 850 degrees Fahrenheit. The ceramic mineral materials that are used in the coating are the same as those used to manufacture glass and pottery. There are no free aluminum atoms contained in the Thermolon properties.
