BASF says its Ultramid polymer meets heat and corrosion protection requirements for EV powertrains

With the development of its heat-stabilized Ultramid B3PG6 BK23238, BASF is expanding its product portfolio of polyamides for the high temperature range. The new P-stabilization offers a heat resistance of up to 190° C and prevents galvanic corrosion on electrical components due to its low-halogenide and metal-free stabilization. The polyamide, reinforced with 30% glass fibers, also protects against thermal aging.

“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,” explained Marketing Manager Andreas Stockheim. 

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.

“Where high temperatures and versatile material properties are required, the new Ultramid can be used. The material convinces with significantly improved aging properties [compared to] 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,” Stockheim added.
