The automotive industry is changing fast, and material suppliers must keep pace with challenging new requirements. At DuPont, we stay a step ahead in the metals to plastics transition with innovative new polymers in the pipeline.

One of the most significant challenges faced by car manufacturers today is CO2 and NOx emissions reduction, and arguably the most effective way to meet toughening emissions legislation is to reduce fuel consumption by rightsizing and turbo charging engines for greater efficiency. Taking weight out of the vehicle is also a key route to achieving those goals, but the question is — how best to reduce weight?

A new White Paper just published by DuPont provides many of the answers by demonstrating that replacement of metals with the latest high-performance polymers may be the most effective way to make a vehicle lighter with the added benefits of easier processing, integration of functions and lowering cost.

Entitled “DuPont High-Performance Polymers for Automotive Air Management Applications”, the step-by-step guide is written to help design engineers and material specifiers meet the latest engine performance, emissions and lightweighting challenges by using the advanced plastics and elastomers developed by DuPont, including DuPont™ Crastin® polybutylene terephthalate, DuPont™ Hytrel® thermoplastic polyester elastomer, DuPont™ Kalrez® perfluoroelastomer, DuPont™ Vamac® ethylene acrylic elastomer, DuPont™ Vespel® polyimide and DuPont™ Zytel® polyamide.

These materials are replacing metals in many air management components, lowering weight by up to 50 percent and costs by some 20 percent compared to metal counterparts, while providing outstanding heat and fluid aging resistance to the hotter, chemically aggressive operating conditions in today’s more compact and increasingly turbocharged engines.

“The automotive industry is changing fast, and material suppliers must keep pace with challenging new requirements. At DuPont, we stay a step ahead in the metals to plastics transition with innovative new polymers in the pipeline to ensure that customers really have the right material for the right application. Being a pioneer in the development of blow moulded air ducts helped us build our expertise in leading edge polymer technology for air management systems,” says Klaus Bender, Global Automotive Air Management Leader, DuPont. “This art-to-part capability is summarized in the new White Paper, and I invite engineers and specifiers across the industry to download the guide here — it will help provide a fast track to advanced plastics and elastomers that provide lightweight solutions for the latest rightsized engines.”

The report reviews emerging market trends and the transition to high performance polymers in air management systems, presents key grades from DuPont’s broad portfolio of rigid and flexible polymers tailored for the automotive industry, highlights successful commercial applications, and explains how the company supports its customers in design, prototyping, processing and laboratory testing. In addition, Section 6 in the white paper entitled “What’s new from DuPont” presents the latest product developments, plus a glimpse of innovations to come.
