Envalior partnered with Flexfab and Steere Enterprises to improve the hot charge air ducts for 2020 Ram 1500 3.0L EcoDiesel trucks in North America. The new ducts leverage Stanyl® Diablo polyamide 46 (PA46), which is formulated specifically for high-temperature blow-molded hot charge air ducts.
The improved ducts now deliver higher peak temperature capability, superior strength, thermal cycling performance, and strength-retention after heat aging compared to PA66-based alternatives.
“To meet the high standards of our OEM customers, we rigorously test a wide range of material solutions for every application, and this project was no exception.” said Pete Hamm, Engineering Manager for Steere. “We chose Stanyl since it delivered a very unique combination of high-temperature performance, robust thermal cycling performance, and processability that was particularly important for this application”

“As vehicle electrification continues its gradual growth, automakers are continuing to seek efficiencies from the internal combustion engine,” said Jud Gibson, vice president for Commercial Americas, Envalior. “This is why our material scientists have developed a diverse portfolio of material solutions designed to reduce weight and improve performance for both traditional and electric powertrains.”
Envalior developed Stanyl Diablo in order to help automakers meet and exceed increasingly stringent global emissions regulations. This has led to a trend in smaller vehicles with downsized engines. Creating these smaller engines requires new part designs. However, air ducts, either in metal or injection molded in plastic, do not offer the design flexibility needed to fit complex under-the-hood geometries. This requires the next generation of materials for hot charge air ducts created using blow molding techniques.
