With the introduction of Ultramid A3U44G6 DC OR (PA66 – GF30 FR), BASF is increasing its portfolio of flame-retardant engineering plastics for the eMobility market. Within the case of already confirmed Ultradur (PBT) merchandise, coloration stability could be largely assured, particularly in orange (RAL 2003) which is in excessive demand within the business. Nevertheless, standard polyamides are likely to robust coloration fluctuations or yellowing throughout warmth growing older.
“Excessive-voltage elements are often uncovered to vital temperature fluctuations. This repeatedly results in robust discoloration in standard polyamides. Our newly developed kind Ultramid A3U44G6 DC OR closes the innovation hole by way of coloration stability and mechanical energy.
—Tina Weller, Product Improvement BASF
The brand new grade meets all the factors of coloration stability and heat-aging resistance and thus additionally permits long-lasting coloration coding, which is safety-relevant within the delicate space of excessive voltages. The colour stability may very well be confirmed after 1.000h at as much as 130°C within the check.
Along with the colour consistency, Ultramid A3U44G6 DC OR with a CTI 600 is characterised by excessive electrical insulation. The usage of tailored pigments whereas on the identical time dishing out with halide-containing flame retardants additionally counteracts electrocorrosion, which was beforehand troublesome to comprise, particularly in humid and heat environments.
Throughout improvement, we targeted on the elimination of halides reminiscent of iodide and bromide, thus setting the course for a sturdy product with out contact corrosion.

With a really low whole halide content material (lower than 50ppm), the PA66 achieves hearth safety class UL94 V0 at 0.4mm. Moreover, the product is supplied with a particular natural warmth stabilization bundle to fulfill the technical market necessities.
