BASF has introduced a new polyphthalamide (PPA) material in its Ultramid range that can be manufactured into semi-finished parts by extrusion.

According to the company, Ultramid Advanced N5H UN has a semi-aromatic chemical structure and has good resistance to chemicals and hydrolysis, even in aggressive environments and improved sliding friction properties, while due to its low water uptake its mechanical properties remain stable over a wider temperature range.

BASF says that the PPA is suitable for extruded pre-fabricated components and small assemblies but also for applications in the automotive industry, in mechanical engineering and in kitchen appliances. During machining, the behavior of the semi-finished products lies between a polyamide and a polyoxymethylene copolymer.

BASF’s polyphthalamide portfolio includes compounds incorporating short-glass, long-glass or carbon fiber reinforcement, and with various heat stabilizers.
