Tata Toyo selected Zytel® PLUS to replace specialty nylon resin product for added protection against the harsh elements associated with turbo-diesel systems. Tata, a leading heat-exchange technology supplier based in Pune, India, also has an eye on replacing metals in other applications.

“Charge air coolers quickly cool hot air generated by the turbocharger before it is forced through the induction system. Cooler air improves combustion efficiency,” said Patrick Ferronato, director of automotive, DuPont Performance Polymers (DPP). “Improving powertrain efficiency while reducing weight and cost is critical to improving fuel economy and reducing dependence on fossil fuels.”

Zytel® PLUS nylon was selected as a replacement to the specialty nylon because it retains rigidity at high temperatures, offers a better surface appearance and processes with ease.

“We have had a long-term relationship with Tata Toyo,” said Avinash Malshe, industry manager, DPP Automotive – India. “When we introduced them to the new materials, they quickly saw the chance to think about where they can use them to deliver better performance and cost. While collaborating, we found more opportunities to capture significant weight savings by replacing metal components and systems.”

Last year DuPont introduced the family of high-performance nylon and PPA materials that deliver long-term resistance to heat, chemicals and pressure. Unlike specialty nylon resins, Zytel® PLUS retains processing ease typical of traditional nylon resins. This family is targeted primarily at automotive underhood and engine applications.
