EcoPaXX®: Hot properties
EcoPaXX® surpasses other green polyamides thanks to a far higher melting point, great stiffness and strength plus chemical resistance – coupled with fast injection molding cycles and a large processing window which help drive increased productivity.
EcoPaXX is 70% bio-based and 100% carbon neutral: It outperforms both PA6 and PA66 because of its superior moisture absorption, better dimensional stability and stiffness (including retention after conditioning) and outstanding resistance to hydrolysis and chemicals like oils, greases and salts.
EcoPaXX has a high melting point of 250°C, providing excellent short and long-term heat resistance - which make it ideal for lighting and Under the Hood applications; as well as extrusion thanks to its stable performance in the melt.
Short term, EcoPaXX has the highest HDT values of all bio-based aliphatic engineering plastics, combined with excellent surface quality and high thermal resistance. Long term the material shows excellent heat-ageing (on a par with PA6 at medium temperatures 150-180 °C).
Continuous use temperatures for Q-HG6
From a processing standpoint, the high melting point and high crystallization rate of EcoPaXX mean quick injection-molding cycles, enabling you to optimize your productivity with faster throughput; and it also offers a broad processing window for flexibility on the production floor.
At ambient temperatures and even elevated temperatures, EcoPaXX grades resist everything from aliphatic hydrocarbons — to automotive liquids like coolants, fuels, oil and grease — to dilute acids, bases and detergents; to aqueous salt solutions such as calcium-and-zinc chloride.
In short, EcoPaXX is like most polyamides in delivering very good chemical resistance , in large part because of its semi-crystalline morphology. However, when exposing any material to serious chemicals we recommend testing under actual operating conditions. At DSM we have the people, experience and resources to help you etablish bespoke testing.
