Kalrez® FFKM Seals for Semiconductor Applications

Kalrez® FFKM seals for semiconductor applications are engineered for ultra-clean environments where chemical resistance, plasma resistance, and contamination control are critical. These perfluoroelastomer sealing solutions are widely used in semiconductor manufacturing equipment including plasma etch, deposition, wet processing, and vacuum systems where standard elastomers cannot withstand aggressive process chemistries or high purity requirements. Kalrez® FFKM materials provide excellent resistance to plasma exposure, harsh chemicals, and elevated temperatures while maintaining low outgassing and low particle generation in sensitive semiconductor processes.


Canyon Components supplies Kalrez® FFKM O-rings, gaskets, and custom parts alongside Canrez® perfluoroelastomer alternatives, offering a competitively priced solution with fast lead times and extremely high quality. Our team supports material selection based on plasma exposure, process chemistry, temperature, and contamination requirements to ensure reliable sealing performance in semiconductor environments.


Common names include: Semiconductor FFKM seals, perfluoroelastomer seals, high purity seals

Features of Kalrez® FFKM Seals for Semiconductor Applications

  • Kalrez® FFKM O-rings, gaskets, and custom parts provide excellent resistance to aggressive semiconductor process chemicals and plasma exposure


  • FFKM materials exhibit low outgassing and low extractables, helping reduce contamination in high purity systems


  • Kalrez® FFKM seals maintain sealing performance at elevated temperatures often exceeding 260°C depending on compound selection


  • These materials offer excellent compression set resistance, supporting long-term sealing reliability in vacuum and process equipment


  • Kalrez® FFKM compounds are available in formulations optimized for plasma resistance, low particle generation, and high purity performance


Limitations of Kalrez® FFKM Seals for Semiconductor Applications

  • Kalrez® FFKM seals have a higher cost compared to standard semiconductor elastomers


  • Lead times may vary depending on compound selection and custom geometry requirements


  • Low temperature flexibility is limited compared to silicone and fluorosilicone materials


  • Certain semiconductor applications may require highly specialized formulations optimized for specific plasma chemistries


  • Over-specifying premium FFKM compounds in less demanding environments can increase cost without added performance benefit

Please consult a Canyon Components Engineer about your specific application and we will use our decades of experience to formulate a solution that fits your need.

Industrial Usage of Kalrez® FFKM Seals for Semiconductor Applications

Kalrez® FFKM seals are used in semiconductor systems where contamination control, plasma resistance, and chemical compatibility are essential. These O-rings, gaskets, and custom parts are widely specified in wafer fabrication and high purity processing environments where seal failure or contamination can impact yield and equipment uptime. Selecting the right Kalrez® FFKM or Canrez® compound depends on process chemistry, plasma exposure, temperature, and vacuum requirements.


Canyon Components provides engineering support to assist with compound selection, sealing design, and contamination reduction strategies. Our team can help evaluate application requirements and provide supporting documentation including Datasheets, TDS, Test Reports, MTR documentation, and MSDS or SDS resources to ensure reliable performance in semiconductor manufacturing systems.
