KetaSpire® KT-820 CF20 is a 20% chopped carbon fiber-reinforced polyetheretherketone (PEEK). The carbon fiber content in the formulation is optimized to provide a balance of strength and stiffness, on one hand, with toughness-related properties, such as impact resistance and elongation at break, on the other. The resin enjoys all the key performance attributes for which PEEK is known. These include resistance to harsh chemical environments, high heat resistance (both short and long term) and excellent fatigue resistance. By virtue of the reduced carbon fiber loading, the resin also offers improved surface aesthetics and reduced anisotropy over comparable 30% carbon-fiber reinforced formulations.
This resin is a low flow / high viscosity grade and is suitable for use in both injection molding and extrusion fabrication. It can be melt processed using standard thermoplastic melt processing equipment.
Potential application areas for  KT-820 CF20 include uses in the oil and gas recovery industry, in chemical processing and in other industrial uses where a balance of part stiffness and toughness is required, such as semiconductor fabrication, automotive, aerospace and healthcare industries.
