Photovoltaic Manufacturing Seals

Photovoltaic Manufacturing Seals Help Improve Uptime

Kalrez® seals can help increase uptime and raise production quantity and quality in bulk crystalline silicon and thin-film photovoltaic processes.

DuPont™ Kalrez® perfluoroelastomer parts resist over 1,800 chemicals and offer excellent thermal stability, making them an appropriate choice for photovoltaic cell manufacturing.

Performance in Cell Manufacturing

Kalrez® W240 and 9100 parts for photovoltaic cell manufacturing offer excellent resistance to both chlorine and fluorine gas, as well as other dry-process chemistry. The seals have excellent mechanical strength properties, and are well-suited for both static and dynamic sealing applications.

The performance properties of Kalrez® seals can help improve reliability, leading to more consistent photovoltaic manufacturing quality, and also more efficient production, with the potential for less down-time.

Chemical Resistance

The aggressive chemicals used in many photovoltaic manufacturing processes can affect the sealing performance of elastomers. Choosing Kalrez® W240 parts as an upgrade over fluoroelastomers and silicone can help prevent or reduce unplanned maintenance and safety incidents as a result of incompatible sealing materials.

Thermal Stability

With heat resistance to temperatures of up to 325O C, Kalrez® PV8070 parts have been designed to incorporate properties that take the heat where fluoroelastomer (FKM) and silicone (VMQ) under-perform. In a comparison of PV8070, FKM and VMQ for over 336 hours at 250°C, Kalrez® seals maintained excellent recovery properties. FKM and VMQ completely lost resilience after 336 hours.
