The world’s first high heat plastic AIM/CAC combination

Kurt Maschke, global segment manager air/fuel, details how DSM developed high-performance materials for air intake manifolds

Kurt Maschke, global segment manager air/fuel


New legislation places very tight limits on car emissions, with strict targets on CO2 emissions. DSM focuses on driving forward solutions that significantly decrease environmental impact, leading to the development of a complete portfolio of thermoplastic products that answer the changing needs of the automotive industry.

One of the latest developments in turbo systems is to integrate the charge air cooler (CAC) into the air intake manifold (AIM), using liquid to more effectively cool the air instead of air-to-air systems. This drives up the temperature in the AIM (currently up to 230°C), as well as the mechanical requirements for the materials used. Integrating the CAC into the AIM reduces the length of piping previously needed to reach the air-to-air cooler in the front of the car, leading to increased engine responsiveness. For car manufacturers, this makes it possible to deliver higher performing engines while still meeting the new emission limits.

DSM offers a complete portfolio of high-performance materials for air intake manifolds whether they have an air-to-air CAC or an integrated liquid-cooled CAC. This includes Akulon polyamide 6, Akulon Diablo, Stanyl and Stanyl Diablo polyamide 46.

Stanyl Diablo OCD 2100 PA46 is the world’s first thermoplastic used for a heat plastic AIM with integrated CAC. To develop the revolutionary AIM/CAC combination, DSM worked closely with the world’s leading producers of engine components. Stanyl Diablo PA46 meets all the challenges of a top-level car with continuous-use temperature of 220°C and the ability to withstand peak temperatures up to 250°C. It combines long-term high performance with low weight and top environmental credentials. Exactly the bright science for carmakers that want to speed up in innovation.
