Solvay PEEK Laminates
Categories: Polymer; Thermoplastic; Polyketone; Polyetheretherketone (PEEK)

Material Notes: Description: Cytec Engineered Materials PEKK composites consist of a matrix of poly(ether-ketone-ketone) polymer with aligned, continuous unidirectional fiber reinforcement. Typical fiber contents are 50 – 60% by volume. The tapes and ribbons are fully impregnated with a tailored fiber-matrix interface for optimal performance. Cytec also supplies custom laminates made from the tapes. The polymer is semi-crystalline with a Tg of 318°F (159°C).* The composites have good structural performance at temperatures in excess of 250°F (121°C). PEKK composites can be used in lightly loaded applications at temperatures up to 400°F (204°C) due to the semi-crystalline nature of the polymer. PEKK composites possess outstanding flame, smoke and toxicity performance. They also have high toughness and damage tolerance. Laminates and parts can be fabricated from PEKK using a wide range of techniques including autoclave and press molding. Prepregs are offered in various grades of PEKK polymer optimized for select manufacturing methods. Information is available upon request for additional grades of PEKK to use in injection molding, sheet, film or fabric composites.
