BASF introduces a tailored portfolio of PA66/6T compounds – Ultramid T6000 – a high-temperature polyamide for electric and electronics (E&E) components, outperforming PA66 in mechanical and dielectric properties in presence of humidity and at elevated temperatures.

Ultramid T6000 is ideal for producing small and complex E&E parts like high-voltage connectors and miniature circuit breakers.

At the same time, its lower moisture absorption ensures good dimensional stability, thus closing the gap to BASF’s Ultramid Advanced PPA portfolio. Ultramid T6000 allows for easy processing at low mold temperatures similar to standard PA66.

Ultramid T6000 are improved, backwards-integrated PA66/6T compounds, which BASF acquired from Solvay in 2020, and are immediately available.

High flowability

Featuring high flowability, Ultramid T6000 is ideal for producing small and complex E&E components, such as high-voltage connectors and miniature circuit breakers (MCB) as well as parts in electric powertrains and consumer electronics.

For example, Ultramid T6340G6 can be used in high-voltage connectors for electric vehicles to provide a safe and reliable connection between battery and inverter or the power distribution and e-motor even at elevated temperatures.

Ultramid T6000 thus helps to transfer power in the most efficient and safe way, even high power surges during swift acceleration can be reliably handled during the whole lifetime of the vehicle, while ensuring an optimum component design in terms of compact, flexible geometry and weight.

Outstanding flame-retardant values

The flame-retardant grades are equipped with a non-halogenated flame retardant.

UL cards for Ultramid T6340G6 show outstanding flame-retardant values. It has a V-0 rating at 0.4mm and is characterized by a high CTI (Comparative Tracking Index) of 600 (acc. to IEC 60112). This supports miniaturization of E&E parts by lower creepage and better insulation than standard PA66.

The PPA provides an excellent electrical RTI (Relative Temperature Index) of 150°C at 0.4mm and a GWFI (Glow Wire Flammability Index) of 960°C at 0.8mm. This ensures functionality for small wall thicknesses, even at high operating temperatures.

Pre-colored and available for self-coloring

Due to its good colorability, compounds with different white shades can be manufactured, in addition to durable orange and grey.

Ultramid T6000 is currently the only pre-colored PA66/6T compounds in durable orange (RAL 2003), which meet the criteria of color stability at high temperatures over a long time.

The compounds enable long-lasting color coding, which is safety-relevant for high voltage applications. The use of tailor-made pigments and non-halogenated flame retardants counteracts electro-corrosion, especially in humid and warm environments.

Besides pre-colored compounds in black, grey, orange and white, UL-certified masterbatches are available for self-coloring. For fuel cell components, the high-purity Ultramid T6300HG7 without flame retardants can be used.
