Carbon PEEK is a carbon-fiber-reinforced PEEK. Carbon fiber improves the compressive strength, stiffness and load capacity of PEEK.
Carbon PEEK has a higher thermal conductivity than unloaded PEEK and therefore reduces its rate of thermal expansion. Together with the chemical resistance typical of semi-crystalline polymers, it offers excellent mechanical properties even near 572 °F (300 °C).
Carbon PEEK offers superlative properties useful for the substitution of metals in more extreme environments.
