Through our proven expertise and collaborative partnerships, DuPont provides tailored solutions for specific industrial challenges. In an effort to develop a more efficient cooling system, BMW and system supplier Mahle selected DuPont™ Zytel® PLUS resin for the integrated indirect charge air cooler of select BMW models: the 740i, X5 4.4i and 340i.

DuPont™ Zytel® PLUS resin is a high temperature plastic with outstanding resistance to chemicals and heat (up to 230 °C), high weldability and excellent flowability. As a nylon, Zytel® PLUS is easy to process. And because it has DuPont’s exclusive SHIELD technology, comprised of high-performing additives, it’s even stronger. And, it has excellent surface appearance.

Thanks to the SHIELD technology, when components made from Zytel® PLUS are exposed to hot oil, hot air, coolant and road salt, they can achieve a service life twice to three times that of parts made from conventional nylons.

Because You Imagined… better performance and fuel efficiency.

Look to DuPont™ Zytel® PLUS. Parts made of Zytel® PLUS:

  • Last two to three times longer than other nylons when exposed to aggressive chemicals
  • Withstand 4,000 hours of exposure to hot air
  • Resist more than 3,000 hours of exposure to hot oil
  • Withstand more than 3,000 hours of exposure to hot automotive coolant
  • Retain the majority of its weld strength after 1,000 hours at 210 ºC, while traditional materials have dropped to almost zero

Giving Shape to Smart Ideas. That’s what DuPont can do with you.
