Teknor Apex’s New Nylon 6/6 Offers Increased Low-temperature Toughness

Published on 2015-07-17. Author : SpecialChem

PAWTUCKET, RI, U.S.A. -- Teknor Apex Company has increased the low-temperature impact strength of a standard toughened nylon 6/6 compound, 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% (see graph).

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 Chemlon 109 HBK778 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.

“Aside from its outstanding low-temperature toughness, Chemlon 109 HBK778 provides physical properties comparable to those of standard Chemlon 109, which has been used successfully in many applications and has received automotive specifications from Chrysler, Ford, and General Motors,” said Michael Roberts, vice president of the Nylon Division of Teknor Apex. “Teknor Apex is prepared to supply this new product worldwide.”
