PPG Industries (Pittsburgh, Pa.) has introduced INNOFIBER specialty glass composition fibers; the company also presented recent laboratory test results from its Shelby, N.C., fiberglass research and development facility. The tests used rovings that paired INNOFIBER glass composition fibers and proprietary sizing chemistry, and the results showed The results, using rovings that paired INNOFIBER glass composition fibers and proprietary sizing chemistry, displayed how these products exceed the corrosion-resistance and modulus-performance limits of standard E-glass. The company says boron-free INNOFIBER CR glass fiber provides good corrosion resistance in acidic environments, and high-modulus INNOFIBER XM glass fibers offer better stiffness and lighter weight for applications that use highly oriented fiber reinforcements.
