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.

Homepage // News Center // PolyOne Launches New ECCOH™ LSFOH Grades for Optical Fiber Cables As global demand for internet connectivity and data transmission capacity continues to rise, fiber optic cable is replacing traditional copper communication cables at a fast pace. Holger Kronimus, general manager for Specialty Engineered Materials at PolyOne said, “As the market for optical fiber cable continues to grow, we are committed to providing innovative material solutions that help customers meet their challenges.

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.

Surface energy match between the thermoplastic elastomers and the rigid thermoplastic substrate. 2. Molecular interaction between the thermoplastic elastomer and the rigid thermoplastic. Table 2 summerizes the data of different polyamide systems; polyamide 6, polyamide 66, glass filled, fiber reinforced , impact modified and heat stabilized.
