For unmodified grades where lower temperatures are found, polyamide 6 provides the better performance. The result: Safer parts (less risk of splintering at low temperatures) and lower breakage levels during processing because parts are tougher coming out of the mold. At lower temperatures this makes it a tougher material – less impact sensitive, less notch sensitive and with ductile behavior at lower temperatures. Polyamide 6 has better ductility than polyamide 66. This offers benefits in terms of stiffness, but disadvantages in terms of part weight and design flexibility. However, for reinforced materials, higher fill levels in polyamide 6 mean grades that deliver the same performance as a polyamide 66, with a lower level of reinforcement. Because polyamide 66 absorbs less than polyamide 6, its performance is slightly better. In hot water environments of 100✬+ polyamides can suffer from hydrolysis – especially when glycol (as an anti-freeze additive) is found (the rate being determined by the amount of water absorbed). For molded parts, they offer an an excellent balance of easy design and processing with outstanding mechanical properties over a wide temperature range and in diverse operating environments. Our Akulon portfolio covers virtually all possible applications with grades suited to all processing techniques, including extrusion, injection and blow molding. Akulon polyamide 6 & 66 resins represent the best value in all-purpose engineering materials. Mineral/glass hybrids for all-around stability and strength.Mineral reinforced grades for better dimensional stability.Individual grades can vary by region, so please check in the product database for more detailed information and availability in your area. From superior impact strength and high heat resistance to excellent flame retardancy, Akulon delivers properties that help you produce greener, lighter and smarter products.
