Applied Science 'Original Works exclusively presented for You' Emissions of volatile organic Compounds from non stick Pans

摘要

Commonly available and marketed frying pans can be equipped with different non-stick coatings. Beside skillets coated with polytetrafluoroethylene polymer (PTFE) based plastics a rising number of articles with ceramic apparels are offered. From material technical point of view the predominant advertising feature for ceramic coated pans is the higher temperature resistance compared to PTFE provided ones. Whereas PTFE polymer is characterized by a decomposition temperature of T-PTFE approximate to 260 degrees C ceramic materials may stand temperature imposition up to T-Ceramic approximate to 400 degrees C. Exceeding material specific usage temperatures the coatings will undergo decomposition reactions with release of toxicological relevant compounds. In previous articles the emission of benzene from PTFE-coated frying pans has been focused on. In the scope of actually run test chamber examinations the thermal resistance of both PTFE- and ceramic non-stick coated pans has been evaluated by exposing the articles to stressing calefaction temperatures under standardized conditioning parameters and quantifying the concentrations of released volatile organic compounds. Gained measuring results of PTFE-coated pans were compared to data of ceramic-coated representatives. Both PTFE- and ceramic appareled skillets show distinct emission profiles under extreme temperature impact. Detected test chamber concentrations were modelled into fictive, additionally resulting indoor air concentrations and evaluated with regard to indoor air hygiene issues.
