CP75BK91 Datasheet

Canrez® CP75BK91 is a 75 Shore A black FFKM compound engineered for ultra-low-temperature sealing applications requiring both flexibility and chemical durability. It provides near-universal chemical resistance and maintains elasticity down to -45°C (-49°F), making it ideal for extreme cold environments where conventional perfluoroelastomers lose performance. With a service temperature range of -45°C to 250°C (-49°F to 482°F), CP75BK91 offers reliable sealing integrity, low compression set, and minimal outgassing across wide temperature variations. Its formulation ensures stable performance during rapid temperature cycling and exposure to aggressive media.

 

CP75BK91 is well-suited for ultra-low-temperature valves, pumps, and sealing systems used in chemical processing and oil and gas industries. It withstands harsh solvents, fuels, and reactive fluids while maintaining sealing strength under cryogenic and high-temperature conditions. This Canrez® formulation combines low-temperature flexibility, chemical versatility, and cost efficiency for dependable performance in demanding environments. Compare to other popular brands of FFKM materials such as Kalrez® 0040 and Chemraz® 564.
