DuPont Performance Polymers (Wilmington, DE) has introduced DuPont™ Zalak® 5300 high-performance seals for photovoltaic cell manufacturing. Zalak 5300 seals bridge the performance gap between standard fluoroelastomers (FKM) and perfluoroelastomers (FFKM) seals. Zalak 5300 seals are specially formulated for use in plasma environments, such as edge isolation, ARC coating in crystalline cell manufacturing, TCO sputtering deposition, and selective a-Si PECVD applications in PV cell manufacturing.
