PA612
Polyamide 612 (PA612) is created through poly-condensation of hexamethylene diamine and dodecanedioic acid.
Special features of PA612 are:
low water absorption and good dimensional stability compared to PA6 or PA66
good resistance to chemicals and weathering
very good resistance to hydrolysis
high melting point of 225°C
problem-free processing
Due to its high melting point, PA612 is especially well suited for pipes and connectors in automotive applications which are exposed to high temperatures. Preferred applications are feed lines for cooling, heating and climate control systems in cars, compressed air lines of heavy-duty trucks exposed to high temperatures, feed lines for hot diesel fuel and individual layers with high barrier properties in multiple-layer petrol lines.
