High performance seals, like Viton® fluoroelastomers and Kalrez® perfluoroelastomer parts, help extend meantime between repair in aggressive downhole applications.
Viton® has been used in the oil and gas exploration, production, refining and upgrading industries for over 30 years to solve critical sealing problems where elastomers such as nitrile or EPDM fail to provide adequate sealing performance.
Kalrez® perfluoroelastomer parts withstand attack from more then 1,800 chemicals solvents and plasmas, and withstand temperatures up to 327°C (620°F). They offer excellent explosive decompression resistance, extrusion resistance in high-pressure applications and excellent chemical resistance to drilling muds, sour gas, amines, cesium-potassium formates and high pH fluids.
As the demand for photovoltaic (PV) systems continue to rise, manufacturers must find ways to increase uptime and improve output. Unplanned maintenance due to incompatible sealing materials can cause downtime and interfere with production schedules.
Selecting the appropriate sealing material can help improve performance and lower cost of ownership in both bulk crystalline silicon and thin film photovoltaic processes that use aggressive "wet" chemistries, high temperatures or reactive plasma/gas. Kalrez® parts retain their elastomeric properties at temperatures as high as 325°C, and resist over 1800 chemicals including alkalis, acids, solvents, O2 and fluorine-based plasma.
The latest sealing product from DuPont, Zalak® 5300 high performance seals, join the Kalrez® perfluoroelastomer product line as a cost-effective alternative in select applications where traditional sealing materials are insufficient. It bridges the performance gap between standard fluoroelastomers (FKM) and perfluoroelastomers (FFKM) parts. Zalak® 5300 parts have been specially formulated for use in the different photovoltaic manufacturing processes.
