high-voltage connectors in inverters, DC-DC converters, and batteries. Due to its high strength and stiffness over a broad temperature range, outstanding chemical resistance, and dimensional stability, the new grade enhances the robustness and reliability of thin-walled HV connectors meeting growing industry needs for halide-free E&E components used in warm and humid conditions. It is available in uncoloured and pre- coloured variants such as the e-mobility standard orange RAL 2003 with high colour stability. Automotive supplier Kostal Kontakt Systeme
uses Ultramid Advanced N3U42G6 in several components in its high-voltage connector KS22 Class 4 for high-current modules as it enables miniaturisation and saves installation space while providing very high electrical insulation which beats aliphatic polyamides, especially at elevated temperatures, and has a high elongation at break so that there is no stress whitening. The material extends the lifetime of E&E components as it is halide-free, thus preventing contact corrosion and subsequent failure of sensitive electrical parts exposed to heat and moisture. The PPA achieves fire protection class UL94 with V-0 at 0.25mm, and due to its low moisture uptake and high heat distortion temperature of 265° C, is especially suited for connectors post-processed with surface mount technology (SMT). “Our new non-halogenated grade combines the
excellent properties of our superhero Ultramid Advanced N with better colourability, long colour stability and outstanding anti-corrosion effect”, said Volker Zeiher from Technical Development Engineering Plastics at BASF. “With this optimised
PA9T, our customers can develop innovative, best-in-class E&E components supported by BASF’s proven flame-retardant expertise and material know-how for electronics manufacturing. Ultramid Advanced N3U42G6 is part of BASF’s tailored flame-
retardant PPA portfolio for the E&E industry that advances the development of challenging parts in consumer electronics, automotive battery systems, and electric powertrains.”
Earlier this year, Syensqo launched its latest
innovation, Amodel PPA HFFR-4133 OR, a high- performance flame retardant PPA distinguished by its vibrant orange colour, which aligns with the industry’s growing emphasis on safety and visibility for critical electric vehicle components. The material retains its bright colour even under prolonged heat exposure, ensuring compliance with industry standards such as ISO 6469-3, IEC 60664, and relevant UL specifications. Deedee Smith, Head of Transportation
Marketing at Syensqo, said: “Our latest innovation not only enhances safety but also offers our clients a pre-coloured orange resin, eliminating the need for in-press colouring and streamlining the manufacturing process.” Amodel PPA HFFR-4133 OR has a V0 rating, making it a suitable choice for high voltage automotive applications. It joins a portfolio of battery solutions including Xencor LFT XTreme PPA LGF-1045 ECHO BP, developed for components requiring thermal runaway protection, and Amodel PPA AE-8945 HFFR, developed for high voltage pyro fuses.

Toyoda Gosei closes the ELV loop
Toyoda Gosei has developed a new technology to recycle high-quality plastic from end-of-life vehicles (ELV) to meet demand for recycled plastic in the automotive industry. Using the technology, the company has developed a recycled plastic with performance equivalent to that of new material even with 50% ELV PP. To achieve this, it has collaborated
28 COMPOUNDING WORLD | August 2025
with fellow Japanese company Isono to procure quality raw materials for recycling and leveraged its original material modification technology, meeting the quality standards for automotive parts for practical application. This technology accelerates horizontal recycling for reuse in the same parts and contributes to CO2
reduction. According to a company survey, this is also the first time in the world that recycled plastic containing 50% ELV plastic has been used in interior parts such as glove boxes that require impact resistance, beginning with the Toyota Camry where it has been used in various components since 2024. The company said it aims to expand applicable products.
