Complēt™ Moisture Resistant Nylons Environmentally Stabilized Nylon 6 and 6/6 Long Fiber Composites Standard nylon 6 and 6/6 materials are a widely deployed class of entry-level engineering polymers that readily accept fiber reinforcement to provide a good mix of mechanical properties at an economical price point. LONG GLASS FIBER SURFACE AESTHETICS Good surface cosmetics with glass fiber reinforced nylons are difficult to obtain without high mold temperatures that lengthen cycle times. Complēt moisture resistant nylons reinforced with long glass fiber produce a smooth, fiber-free finish without special processing to give molded components a high-quality appearance.

TOUGH ENOUGH TO PROTECT THE POWER GRID MODULAR BALLISTIC PROTECTION MADE POSSIBLE WITH COMPOSITES THE CHALLENGE Recent attacks on U.S. electrical substations across the country provide stark reminders that our nation’s power supply remains a primary target for criminals focused on harming our country and security.1 The call to action is evident: we must continually improve the physical and technological infrastructure protection of our nation’s energy supply. THE SOLUTION Ballistic-resistant panels made with fiber-reinforced polymer (FRP) composites offer key properties that enable Southern States to meet its customers’ critical needs. THE IMPACT Southern States’ ballistic-resistant solutions incorporate three layers of uniquely formulated GlasArmor composite panels to achieve Underwriters Laboratories (UL) Level 8 protection.

CLEVELAND – In response to growing customer demand for metal replacement, PolyOne Corporation (NYSE: POL) is expanding capacity for its OnForce™ LFT long-fiber specialty thermoplastics. PolyOne’s robust glass- and carbon fiber-filled formulations retain aesthetic appeal in metal replacement and structural applications, while also offering higher stiffness, impact strength and surface finish than short-fiber filled materials. Demand continues to increase for lighter weight materials, and the products made from them.

Composition Vectran® is an aromatic polyester spun from a liquid crystal polymer in a melt extrusion process. This process orients the molecules along the fiber axis, resulting in a high tenacity fiber. We believe that our ongoing commitment to protect the environment, to remain at the forefront of fiber and coating technology, and to ‘treat others as we want to be treated’ will continue to drive the success of our customers, shareholders, and employees.
