Heat-Resistant Polyamide Ultramid® Endure in the 2017 Alfa Romeo Giulia : BASF of Germany has announced the use of Ultramide at one of the models of the Alfa Romeo. Please read the text at the following paragraphs:
Corbetta,/Italy, Toronto/Canada, and Ludwigshafen/Germany, May 9, 2017. BASF is introducing its heat-resistant polyamide Ultramid® Endure in two new powertrain applications on the 2017 Alfa Romeo Giulia: the air intake manifold with integrated charge air cooler and the hot-side turbo duct. As heat under the hood increases, Ultramid® Endure with its high heat-aging resistance up to 220°C enables automakers to achieve engine downsizing and turbocharging without sacrificing performance. The Ultramid® Endure grades offer good processability, excellent weld line strength and are available globally.
Hot-side turbo duct by ABC Group made of Ultramid® Endure D5G3 BM
BASF collaborated with the automotive supplier ABC Group, Canada, to develop the hot-side turbo duct for the Alfa Romeo Giulia. For this application, ABC Group decided on BASF’s Ultramid® Endure D5G3 BM, a 15 percent glass fiber reinforced blow molding grade, which has a high hose strength and shows good swelling.
ABC Group leveraged BASF’s joining technology expertise to optimize the infrared (IR) welding parameters for this part. It was crucial to achieve strong weld lines to ensure the long-term durability of the duct. “After conducting numerous resin trials through molding, welding and rigorous validation testing, we were able to meet the significant demands on this application,” said Mary Anne Bueschkens, CEO of ABC Group. “The part requires many weld connections. Our engineers worked closely with BASF’s material and joining experts to understand the unique requirements, allowing us to fine-tune our IR welding technology, and assuring success of the welding process for this demanding high-temperature duct.”
Air intake manifold with integrated charge air cooler by Magneti Marelli made of Ultramid® Endure D3G7
BASF worked with Magneti Marelli, a business of Fiat Chrysler Automobiles (FCA), to develop the air intake manifold with integrated charge air cooler for the Alfa Romeo Giulia. The need for a material to withstand a 200°C continuous use temperature made this air intake manifold a prime candidate for Ultramid® Endure D3G7, a 35 percent glass fiber injection molding grade. The air intake manifold also required an excellent burst pressure performance; therefore, Magneti Marelli needed a material that offered reliable weld strength at elevated temperatures.
