CYCOM® 2237 is a 600?F (316?C) curing polyimide resin system with a service temperature range up to 550?F (288?C) and is Solvay’s version of PMR-15. It is formulated for high temperature applications where low void content is critical.  CYCOM® 2237 has an excellent overall balance of processing behavior, thermo-oxidative stability, and retention of properties in the 500 to 550?F (260 to 288?C) range. CYCOM® 2237’s thermo-oxidative stability and micro-crack resistance make it ideal for jet engines and other fatigue loaded components like bypass ducts, gear box covers, transmission housings, vent tubes, fan stator and vane assemblies, nozzle flaps, core cowls, particle separator swirl frames, and compression molded bearings. 

CYCOM® 2237 prepreg can be autoclave cured, vacuum bag processed, or compression molded.

CYCOM® 2237 is solution impregnated on a variety of fibers and fabrics. It is currently available on glass, quartz, and graphite reinforcement.
