Thermal Management Solutions PANEX® 30 products are PAN based materials that are >99% carbonized. These high-purity products are derived from Zoltek’s high temperature batch carbonization process. They are most often used in extreme applications that demand resistance to harsh temperature and chemical environments. All PANEX® 30 materials are thermally stable and chemically pure. Rovings & Spun Yarns: PANEX® 30 carbon fiber yarns are >99% carbonized and have a density of 1.75 g/cc. These yarns are characterized by their many surface fibrils protruding in various directions, making them ideally suited for high performance applications including carbon/carbon and other refractory composites. Rovings & Spun Yarn Applications: • Used for carbon/carbon preforms • Braided compression packings and seals Carbon Content Tensile Strength Tensile Modulus Yield Denier Twist Direction Technical Data for High Twist Roving Woven Fabrics: PANEX® 30 woven carbon fiber fabrics made from spun yarn that is tailored for a variety of finished composite thicknesses. These fabrics have high cross-ply tensile and interlaminar shear strengths in composite materials. Another advantage of these fabrics is their contour conformation without wrinkling. PANEX® 30 fabrics are thermally stable and chemically pure with low oxidation rates. Carbon Content Density Oxidation Rate Woven Fabric Applications: • Aircraft & automotive brakes • Clutch plates • Gas diusion layer for fuel cells

Thermal Management Solutions Felts: Zoltek’s needlepunched felt is produced from PYRON® oxidized PAN fibers and later carbonized to >99% carbon Felts Applications: content in our vacuum furnaces.
