Kalrez® stable in harsh environments specialty sealing engineered for your mission-critical applications.
From aerospace and chemical processing to chip manufacturing and oil and gas/renewable energy applications, DuPont™ Kalrez® elastomers are engineered to provide more stability, more resistance, and more effective sealing.
While DuPont didn’t invent o-rings or specialty sealants, it has a 40-year track record of innovation and development, creating sealants that stand up to the most challenging operating environments.
Aside from its cleanliness and purity, Kalrez® polymer chains are engineered to be one of the most inert polymer structures available, standing up to more than 1,800 different chemicals while offering high-temperature stability.
Kalrez® perfluoroelastomer parts are manufactured to the highest quality standards. Every part has documented traceability, and these parts provide one of the longest, most predictable lifespans in industry.
The long-term, proven performance of Kalrez® parts can mean less frequent seal changes, repairs, and inspections, increasing process and equipment uptime for greater productivity and yield.

Kalrez® perfluoroelastomer parts for innovative sealing technologies
Specialty sealing offering long-term, proven performance in the harshest and most demanding environments.
Kalrez® Rapid Gas Decompression Testing
Available in a number of different compounds, Kalrez® parts are formulated to optimize properties giving the best possible performance in various chemicals and temperatures.
Innovation Using Kalrez® and Vespel®
Kalrez® 9100 parts were tested in critical seal positions and expected to double or even triple the lifetime of seals in HDPCVD processes.
Advantages
Chemical resistance
Available in a number of different compounds, Kalrez® parts are formulated to optimize properties giving the best possible performance in various chemicals and temperatures.
Heat resistance
DuPont heat resistant plastics offer cost-effective, application-optimized choices to replace metal, ceramics and other polymers in a range of uses.
Rapid gas decompression
Reduce potential for seal failure with Kalrez® O-rings which have been certified by two independent labs to meet rigorous requirements for resistance to rapid gas decompression.
Minimize wafer contaminations
Purity is critical to wafer yield. Specially-formulated Kalrez® FFKM seals reduce wafer contamination from particles, outgassing and extractables.
Outgassing performance
DuPont™ Kalrez® bonded door seals are designed for easy installation and low particle generation.
Kalrez® sealing solutions for oil & gas
Kalrez® perfluoroelastomer parts provide best in class chemical resistance for exploration and production services while also meeting the industry standard requirements.
