BASF-powertrain-Pa BASF has expanded its product portfolio of polyamides for the high-temperature range with the development of the heat-stabilized Ultramid® B3PG6 BK23238. The polyamide, reinforced with 30% glass fibers, impresses with excellent thermal aging performance, as well as vibration and hot gas welding properties.

The new P-stabilization offers a unique heat resistance of up to 190 °C and prevents galvanic corrosion on electrical components due to its halogenide- and metal-free stabilization (halogenide content: <50ppm).

Innovative P-stabilization for Multiple Applications

Heat resistance, good long-term use properties and weld resistance are the basic prerequisites for components in current and future powertrains. Whether in the internal combustion engine as well as in the hybrid or electric vehicle, reliable and technically flawless materials are indispensable in a demanding environment.

"Some customers were looking for a PA6 standard material that meets temperature requirements of up to 190°C. In addition, metal-free heat stabilization is requested more often in order to protect sensitive electronic components in various powertrain technologies from galvanic corrosion and thus to avoid possible failures," explains Andreas Stockheim, segment marketing manager powertrain and chassis in BASF's performance materials division. "The developed material with the innovative P-stabilization can not only be used in conventional environments, but is also suitable for electronic applications, such as in electric vehicles."

Heat Stabilization for Electric Powertrains

During the development of the new material with a focus on components in the charge air duct, the versatility of the glass fiber reinforced Ultramid® was analyzed. For the first time, high temperature requirements were realized by the new heat stabilization. The best conditions for use in electric powertrains. With the Ultramid® B3PG6 BK23238, BASF is adding another product grade to its versatile portfolio of glass fiber reinforced and heat resistant polyamides.

The new Ultramid® can be used where high temperatures and versatile material properties are required. The material convinces with significantly improved aging properties than existing PA6 GF30 systems, which are currently available on the market. Due to the versatile, cross-industry application possibilities, we can provide large production volumes at economically attractive conditions.
