Case Studies

Mazda SKYACTIV-D diesel engine boosted by turbocharger parts

Mazda was looking for parts that would be durable under an extremely high temperature, high pressure and wet environment. But it was not possible to produce such pipes by injection molding without the technological expertise and support from DuPont, which we could not get from a part supplier. As a result, we chose DuPont as the only materials supplier that could provide both a plastic and rubber solution for this application.
