Zyron Zyron is a registered trademark for specialty gases marketed to the global electronics industry by DuPont. == History ==
Freon was used as the original brand name for electronic gases produced and marketed by DuPont. With the depletion of the ozone layer and the subsequent phase-out of chlorofluorocarbon (CFC) gas compounds, the company rebranded this product line to differentiate from refrigerant gases that had been using the same Freon brand name. The name was developed in October 1991 by DuPont employees Paul Bechly and Dr. Nicholas Nazarenko, was first used in commerce on June 12, 1992, and became a registered trademark of DuPont in 1993.〔(USPTO Trademark Registration # 1772141 )〕
