In industries where reliability and durability are non-negotiable, choosing the right sealing solution is critical. Enter the Kalrez O Ring, a high-performance perfluoroelastomer sealing component developed by DuPont™ that excels in the most demanding applications. From semiconductor manufacturing to aerospace, chemical processing, and pharmaceutical industries, Kalrez O Rings offer unparalleled chemical resistance, thermal stability, and longevity.
What is a Kalrez O Ring?
A Kalrez O Ring is a sealing ring made from DuPont’s proprietary perfluoroelastomer (FFKM) material. Unlike standard elastomers, Kalrez combines the chemical resistance of polytetrafluoroethylene (PTFE) with the flexibility of elastomers, making it uniquely suited for extreme environments. It withstands temperatures up to 327°C (620°F) and resists over 1,800 chemicals, including acids, bases, amines, oxidizers, and solvents, which are often challenging for conventional sealing materials.
Key Features of Kalrez O Rings
Exceptional Chemical Resistance: Kalrez O Rings maintain integrity against a broad spectrum of aggressive chemicals, including organic and inorganic acids, amines, ketones, and oxidizing agents.
High Thermal Stability: They perform reliably at continuous temperatures up to 327°C and tolerate short-term excursions beyond this limit.
Low Compression Set: Kalrez exhibits excellent resistance to permanent deformation, ensuring consistent sealing performance over long service intervals.
Purity and Cleanliness: Manufactured to stringent standards, Kalrez parts minimize extractables and particulates, critical for semiconductor and pharmaceutical applications.
Traceability and Quality Control: Each Kalrez component is produced under strict quality standards with full traceability, guaranteeing predictable lifespan and performance.
