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.
