PAWTUCKET, US: Teknor Apex Company’s two new glass fiber-reinforced polyamide compounds from exhibit outstanding flame retardance and exceptional thermal stability for injection moulded under-hood automotive components such as engine covers, the company said.
Chemlon 904-13 GVNH and 204-13 GVNH BK091 are glass-filled nylon compounds with low halogen content that meet the UL-94 V-0 standard by passing the vertical burn test at a thickness of only 0.8 mm (0.031 in.).
Conventional halogenated compounds achieve this degree of flame retardancy only with high levels of flame retardant and synergistic filler that make processing difficult, yield poor surfaces and increase product density. In contrast, the new Chemlon compounds yield a smooth surface, are 15 percent less dense than conventional counterparts and are readily processed for parts with long flow paths or thin walls.
“Equally valuable for under-hood applications is the thermal stability of the new compounds. Chemlon 904-13 GVNH is an especially high-temperature material, with a heat deflection temperature of 245 °C [473 °F] and a high degree of property retention at elevated temperatures. In fact, this compound provides a continuous use temperature that is much higher than specification,” according to Jeff Schmidt, automotive industry manager for the nylon division of Teknor Apex.
