Nylon 6/6 compound offers low-temperature toughness for range of injection molded applications

17-Jul-15

The low-temperature impact strength of a standard toughened nylon 6/6 compound has been increased by Teknor Apex Company, providing enhanced cold-weather performance for injection molded applications as diverse as fasteners, fuel can nozzles, cable ties, living hinges, and sports equipment. New Chemlon® 109 HBK778 exhibits 50% greater notched Izod impact strength at -40 °C than the company’s standard Chemlon 109 product, a toughened nylon 6/6 compound. At -10 °C, it still provides nearly as much impact resistance as it exhibits at room temperature, whereas that of standard Chemlon 109 has fallen by 75%. Among the key physical properties of Chemlon 109 HBK778 are notched Izod impact strength of 18 kJ/m2 at – 40 deg. C., and flexural strength of 52 MPa (see table). Good flow properties make it suitable for intricate parts such as clips and fasteners, where the flexural strength of the material enables it to withstand the stresses of assembly and end use.
