Chemical trade large BASF has added a brand new product to its portfolio of PPAs (polyphthalamides, a kind of thermoplastics). The brand new Ultramid Superior N3U42G6, a polyamide 9T with non-halogenated flame retardant, is designed to reduce electro-corrosion of metallic contacts in electrical and electronics elements for e-mobility. BASF says its new PPA will increase the protection and sturdiness of high-voltage connectors in EV parts together with inverters, DC-DC converters and battery packs.
“Because of its excessive energy and stiffness over a broad temperature vary, its excellent chemical resistance and dimensional stability, the Ultramid Superior N grade enhances the robustness and reliability of thin-walled high-voltage connectors, assembly rising trade wants for halide-free parts utilized in heat and humid circumstances,” says BASF.
Ultramid Superior N3U42G6 is accessible uncolored with UL-certified masterbatches, or pre-colored. It boasts excessive colour stability and wonderful colour retention after warmth ageing.
German automotive provider KOSTAL Kontakt Systeme makes use of the brand new Ultramid Superior N in a number of parts in its high-voltage connector KS22 Class 4 for high-current modules. The corporate’s HV-connector, the smallest in its efficiency class, advantages from the BASF PPA in a number of methods: the brand new PPA permits miniaturization and saves set up area, because it reveals good flowability at skinny wall thickness; it gives the connector with very excessive electrical insulation—superior to that of aliphatic polyamides, particularly at elevated temperatures. Lastly, it has a excessive elongation at break in order that there isn’t a stress whitening when the totally different parts are mounted.
Ultramid Superior N3U42G6 is halide-free (in response to EN 50642), so it prevents contact corrosion and extends the lifetime {of electrical} and digital parts. The PPA achieves hearth safety class UL94 with V-0 at 0.25 mm. It additionally permits long-lasting colour coding—in in-house assessments, colour stability was confirmed after 1,000 hours at temperatures of as much as 150° C.
“Our new non-halogenated grade combines the superb properties of our superhero Ultramid Superior N with higher colorability, lengthy colour stability and excellent anti-corrosion impact,” says BASF’s Volker Zeiher. “With this optimized PA9T, our prospects can develop modern, best-in-class parts supported by BASF’s confirmed flame-retardant experience and materials know-how for electronics manufacturing.”
