Product functions: Medium Service Temperature (70°C to 150°C)

Solvay’s APC (PEKK-FC) composites consist of a thermoplastic matrix of poly (ether-ketone-ketone) commonly referred to as PEKK-FC polymer with aligned, continuous unidirectional fiber reinforcement. The tapes are fully impregnated with a tailored fiber-matrix interface for optimal performance. Solvay also supplies custom laminates made from the tapes.
The polymer is semi-crystalline with a glass transition temperature of 318°F (159°C). APC (PEKK-FC) composites possess outstanding flame, smoke, and toxicity performance. They also have high toughness and damage tolerance. Laminates and parts can be fabricated from APC (PEKK-FC) using a wide range of techniques including autoclave and press molding.
Typical applications for Solvay’s APC (PEKK-FC) include aircraft structure, space components, and other transportation & structural engineering components.
