BASF announced that its range of Ultramid polyamide (PA) and Ultradur polybutylene terephthalate (PBT) are now available globally for equipping vehicle interior and exterior high-voltage plug-in connectors.
Switzerland-based TE Connectivity is one of the first companies to produce connectors for hybrid and electric vehicles (EV) using various Ultramid grades.
The high-voltage connectors can be identified by their orange color. As said, the light-colorable BASF PA used is color stable and resistant to thermal aging, since the color coding of the individual components needs to remain highly visible for at least 10 years.
Both the Ultramid and Ultradur grades pass the test according to the tighter IEC standard 62196-1 and the glow wire test according to IEC 60695-2-11 – at 850°C for parts made from isolating matter which holds conducting parts, and at 650°C for all other parts made from isolating matter
According to BASF, the materials for plug-in connectors close to the battery are resistant to high temperatures as well as coolants and equipped with flame retardant if necessary.
Meanwhile, materials used for plug-in connectors in the charging system are noted among other things for their flame retardance, impact strength and creep resistance as well as superior isolation properties.
BASF added that it also supplies plastics which contain halogen free flame retardant (HFFR) and comply with the Restriction of Hazardous Substances Directive (RoHS).
