Solvay (Brussels, Belgium) has launched Omnix LF-4050 and Omnix LF-4060, high-performance polyamides (HPPA) with long fiberglass content of 50% and 60% respectively. These materials are designed for applications subjected to permanent load or operating conditions where metal is prevalent, particularly where the high temperature or hydrolytic stability of performance limits of PA66 are reached. The ductility of Omnix LF grades, says Solvay, shows up to 350% higher notched and multiaxial impact strength, while preserving material stiffness. The company also reports that Omnix LF grades exhibit high property retention under heat and moisture. When compared to standard glass-filled HPPA, the LFT technology is said to offer stiffness improvement of 10-15% at 23°C/73°F, and 85% at 120°C/248°F. Both grades exhibit low warpage and are hot-water moldable.
