PEKEKK
Polyetherketoneketone
PEKEKK belongs to the PAEK family and has even higher temperature resistance than PEEK, with continuous use up to 280 °C. The material has excellent chemical resistance and retains its mechanical strength even at extreme temperatures. PEKEKK is inherently flame retardant with very low smoke development. The material is used in the aerospace and space industry, oil and gas industry and other applications where extreme temperatures and chemical stress occur simultaneously.
