Kalrez® and Zalak® seals in Photovoltaic Manufacturing Processes


Description

As the demand for photovoltaic systems continues to rise, manufacturers must find ways to increase uptime and improve output. Frequently, more aggressive and efficient chemicals, and/or higher temperatures are employed to increase throughput; thereby, putting more strain on the manufacturing infrastructure. Unplanned maintenance due to incompatible sealing materials can interfere with production schedules causing downtime. As a result, sealing materials in either wafer-based or thin film processes should have broad chemical compatibility and excellent thermal stability.

DuPont™ Kalrez® perfluoroelastomer parts have been field proven in highly aggressive sealing environments for more than 30 years. Kalrez® parts can help improve sealing reliability in photovoltaic processes that use high heat, aggressive chemicals and plasma. Kalrez® seals resist over 1,800 chemicals including reactive gases and plasmas, alkalis, acids and solvents. Even in contact with these corrosive chemicals, Kalrez® seals retain their elastomeric properties at temperatures as high as 325 °C.

The latest sealing product from DuPont to provide optimal performance, Kalrez® W230 perfluoroelastomer parts are the choice in PV wet and select dry processes as an upgrade from standard elastomers. W230 provides an excellent combination of properties (resistance to acids/bases), along with the proven performance expected from DuPont™ Kalrez® perfluoroelastomers parts.
