BASF has unveiled a new flame-retardant (FR) grade of Ultramid T6000 polyphthalamide (PPA), now employed in terminal block applications to enhance safety in the inverter and motor systems of electric vehicles (EVs).
Ultramid T6000 bridges the performance gap between traditional PA66 and PA6T, delivering better mechanical and dielectric properties, even under humid conditions and elevated temperatures. Its easy processing and low tool corrosion make it ideal for complex automotive designs. The material also offers a wide range of pre-colour options, including vibrant shades, combining aesthetic flexibility with high performance.
'As safety becomes increasingly vital in designing EV components like wiring terminals and busbars, BASF remains committed to creating innovative solutions that meet today’s demands while equipping customers with tools for future challenges,' said Eng Guan Soh, Vice President, Business Management Engineering Plastics, Performance Materials Asia Pacific at BASF.
The FR grade of Ultramid T6000 is tailored for EV applications, offering high strength and durability for terminal blocks. Its ability to withstand extreme thermal shock—from -40°C to 150°C over 1,000 cycles—ensures long-term reliability. Additionally, its excellent electrical isolation properties enhance safety on the 800V platforms used in modern EVs. The non-halogenated flame-retardant formulation reduces the risk of metal corrosion while meeting stringent safety standards, protecting vehicle occupants in case of fire.
The material’s outstanding strength, stiffness, and dimensional stability enable the creation of complex designs, facilitating the integration of multiple functions into single components. This simplifies assembly, optimises space efficiency, and supports the evolving requirements of EV manufacturing.
