Perfluoroelastomer — near-universal chemical resistance plus extreme heat — for the harshest sealing environments.
Chemical resistance approaching PTFE with elastomeric recovery — the highest-performance sealing elastomer for critical, no-fail service.
FFKM (Kalrez is a DuPont trade name) is fully fluorinated, with chemical resistance approaching PTFE while retaining elastomeric recovery. It withstands aggressive acids, bases, solvents, amines and steam at temperatures well beyond FKM. It’s the highest-performance — and highest-cost — sealing elastomer, reserved for critical applications.
Typical published ranges — final properties depend on the specific ARC compound, cure system and fillers. Request a compound-specific data sheet for design values.
Wafer-process chamber, valve and RF seals exposed to plasma and aggressive chemistries.
Pump, valve and reactor seals for mixed and aggressive media.
Extreme sour-service and high-temperature downhole seals.
High-purity process seals for CIP/SIP and aggressive cleaning agents.
