DuPont Packaging & Industrial Polymers Technical Paper at Bioplastics "Reshaping an Industry Conference," Display Stimulates New Ideas


Making the Most of Renewably Sourced Polymers

WILMINGTON, Del., Jan. 26, 2011 – The many ways bio-based materials can enhance performance and meet consumer demand for environmentally responsible products were explored in a talk by Carol Casarino, Ph.D., former global technology manager, DuPont Packaging & Industrial Polymers, at the inaugural Bioplastics "Reshaping of an Industry" Conference, Feb. 1-3, 2011, at Caesars Palace in Las Vegas, Nevada.

“As consumers demand more renewably sourced durable and disposable products, the number of materials available to manufacturers is growing rapidly – it’s hard to keep up,” said Casarino.  “With the market poised for double-digit growth over the next few years, opportunities to network and share information are important to developing new products that meet consumer demand.”

Casarino will present “Perspectives on Partially Bio-Based Materials,” which focuses on bio-content sources, coupling agents and compatabilizers, on Wednesday, Feb. 2, at 2:30 p.m.

DuPont led the industry with the first families of high-performance renewably sourced materials to help reduce dependence on fossil fuels.  These materials include: DuPont™ Biomax® resins and modifiers for the packaging industry; DuPont™ Sorona® polymer for fabrics and fibers; and DuPont™ Hytrel® RS thermoplastics polyester elastomer, Zytel® RS nylon and Sorona® EP thermoplastic polymer for automotive and other consumer industries.


Renewably sourced DuPont™ Zytel® RS nylon is used in the Toyota Camry radiator end tank, honored with the Most Innovative Use of Plastics award in the Environment Category from the Society of Plastics Engineers (SPE) Automotive Division.
Joint development work between Takata Petri of Aschaffenburg, Germany, and DuPont has resulted in the launch of a new grade of DuPont™ Hytrel® RS, the industry’s first renewably sourced thermoplastic elastomer for use in airbag systems.

Giving Shape to Smarter Ideas

This broad portfolio is used in many products across multiple industries.  At the conference, DuPont will show a Calvin Klein Golf jacket made with 100 percent Sorona® "shape memory" fabric, Toyota PRIUS floor mats made with Sorona® polymer, the award-winning Denso/Toyota radiator end-tank and Fisher wall plugs using Zytel® RS nylon. 

Concepts include: 

  • Samples that show how Biomax® Strong PLA Toughening Modifier for bio-based and compostable polylactic acid (PLA) packaging can improve toughness and reduce brittleness — without sacrificing product clarity.


“The opportunity to touch, feel, explore and talk about these new materials stimulates new ideas for durable and disposable products that not only reduce environmental impact, but improve the product’s performance,” said Casarino. “Performance improvement is an important distinction for renewable materials.”

DuPont – one of the first companies to publicly establish environmental goals 20 years ago – has broadened its sustainability commitments beyond internal footprint reduction to include market-driven targets for both revenue and research and development investment. The goals are tied directly to business growth, specifically to the development of safer and environmentally improved new products for key global markets.
