The number of passenger vehicles with turbocharged engines is expected to increase 80% globally by 2017 according to projections released by Honeywell Transportation Systems (Morris Township, NJ). This change is driven by increased demand for automobiles that deliver fuel efficiency, performance, and reduced greenhouse gas emissions.
This increased used of turbochargers is spurring demand for engineering plastics able to tolerate the elevated temperatures that result underhood. One new option now available for sampling is a high-heat (HH) grades of polyphthalamide (PPA) resin grades that can reportedly extend the service life of components used in high-temperature air induction applications such as air cooler housings, resonators, charge air hoses, and components for exhaust gas recirculation. These components are employed in turbochargers....
