Perfluoroelastomer and Fluoroelastomer Seals for Photovoltaic Cell Manufacturing Processes


Description

Photovoltaic (PV) cell manufacturing involves the use of many aggressive chemicals and operates under very severe environments, including high temperatures and reactive plasma. As more aggressive processing variants and technologies are used to help increase equipment uptime and cell efficiency, more strain is placed on the manufacturing process. Sealing performance can vary dramatically; thus selecting the appropriate sealing material can help reduce unscheduled downtime, product loss and safety concerns to the work environment.

Perfluoroelastomers and fluoroelastomers are widely used as seals in PV cell manufacturing equipment due to their extraordinary resistance to chemicals and heat. The first commercial perfluoroelastomer was developed in 1968 by E.I. duPont de Nemours. It was sold as parts (seals) under the trade name DuPont™ Kalrez®. The first commercial fluoroelastomer was produced by E.I. duPont de Nemours in 1957. It was sold under the trade name DuPontTMViton® (Viton® A). From this beginning, the use of perfluoroelastomers and fluoroelastomers has increased steadily as application requirements have become more stringent. Today, perfluoroelastomer and fluoroelastomer seals are manufactured by a number of companies worldwide including DuPont.
