Pred Materials International, Inc.: Continuous Alumina Fiber
March 1, 2001
Nitivy continuous alumina fiber was developed under a cooperative agreement between Japan’s Denki Kagaku Kogyo K.K. and Nitivy Co., Ltd. The polycrystalline fiber contains 70% Al2O3 and 30% SiO2. With a standard diameter of 10 micrometers, Nitivy has recently developed a commercially available 7 micrometer filament as well. Yarns are bundled in several thousand filaments and have excellent flexibility. Characteristics of the fiber include excellent heat resistance—no strength loss and no heat shrinkage occurs up to 1200°C. The fiber’s high strength and high modulus make it suitable for reinforcing materials, and it offers excellent chemical resistance and electrical insulation ability.
