CP90BK21 Datasheet

Canrez® CP90BK21 is a 90 Shore A black FFKM compound engineered for ultra-low-temperature sealing applications that demand both rigidity and chemical durability. It provides near-universal chemical resistance and maintains elasticity down to -46°C (-51°F), making it ideal for environments where conventional FFKMs lose flexibility. With a service temperature range of -46°C to 220°C (-51°F to 428°F), CP90BK21 delivers reliable performance and dimensional stability in extreme cold and chemically aggressive conditions. Its high durometer design ensures excellent extrusion resistance and long-term sealing integrity under pressure.

 

CP90BK21 is well-suited for ultra-low-temperature valves, pumps, and sealing components in chemical processing and oil and gas applications. It resists degradation from harsh solvents, fuels, and process fluids while maintaining strength through thermal cycling. This Canrez® formulation combines high durometer strength, low-temperature flexibility, and broad chemical compatibility for dependable performance in demanding cryogenic and industrial environments. Compare to other popular brands of FFKM materials such as Kalrez® 0090 and 0040.
