DuPont makes a sustainable presence at K 2007

DuPont’s commitment to a sustainable agenda is reflected in its presence at K 2007, Düsseldorf (Germany), October 24-31, 2007. Highlights of the company’s exhibit will include latest developments in terms of polymer production from renewable sources, and metal replacement for energy saving and reduced emissions. New products for enhanced performance across a range of industries like automotive, healthcare, packaging, electrical, chemicals, sports and leisure – will also feature prominently in commercial applications from across the world, while further detail will be provided on the capability of the recently-inaugurated multilayer and corrugation extrusion line at DuPont’s European Technical Center in Geneva. The DuPont stand is in Hall 6, Stand D27.

Renewably-sourced materials

One of the early proponents of bio-sourced materials, DuPont is already processing corn grain to make Bio-PDO™ at a facility constructed with Tate & Lyle, which was officially opened in June 2007. DuPont is now exploring the refining of other cellulosic materials, such as corn stover – the residual from the plant that remains after the corn is harvested – to sugars for processing into value-added chemicals such as Bio-PDO™. In 2008, the company is expected to participate in the construction and operation of a pilot cellulosic biorefinery to ethanol. “With the growing demand for sugars for industrial intermediates and biofuels, cellulosic conversion is an essential step in a biorefinery concept,” comments Dr. Nandan Rao, technology director for DuPont Performance Materials.

Superstructural resins

In another new technology announcement, DuPont is focusing on improving the performance of its materials through both nanotechnology and more efficient methods of polymer reinforcement, as the company works to push the properties of polymer composites further in the direction of metals. The company’s most recent steps involve a superstructural family using a combination of high-performance polyamides and glass or carbon-fiber reinforcement to provide new levels of stiffness and strength. High strength structural materials have been made possible with elevated concentrations of standard short-glass-fibers that required innovations in compounding technologies. Thermoplastics reinforced with long-glass-fibers move them further up the metals replacement curve for applications where light weight and high strength are critical. Further improvements will come from metal/plastic hybrids, fabric-reinforced thermoplastic composites and long carbon fiber reinforcement.

Progress in thermoplastic nanocomposites

Since its announcement during 2006, DuPont’s proprietary nanocomposite technology has made significant progress, as the company increases its understanding of the properties attainable as it reduces the particle size of reinforcing materials to increase the interfacial area by an order of magnitude. Significant improvements in crystallization, rheological, mechanical and permeability properties can be achieved for improved processing, better structural performance, higher heat deflection temperatures, better electrical insulation and improved barrier to gas permeation. DuPont research is focused on a range of polymer matrices including polyester and polyamides.

New multilayer and corrugation line installed at ETC in Geneva

Moving from product to technical support, DuPont has extended the range of extrusion processes available to its customers with the inauguration of a new multilayer and corrugation extrusion line at its European Technical Center (ETC) in Geneva, Switzerland. The adjustable line includes a three-layer crosshead for multilayer tubing applications, while a corrugator in the same line enables the production of flexible, corrugated monolayer or multilayer tubes for piping applications, predominantly for the automotive and industrial sectors. The strategic investment by DuPont marks the company’s long-term commitment to extend its material and technical expertise to the growing extrusion sector.

A breadth of materials for a range of applications

commercial applications of DuPont high-performance thermoplastics

Recent commercial applications of DuPont high-performance thermoplastics to be presented at K-2007 include those for the automotive, industrial, consumer and healthcare sectors. Those selected reflect current trends among customers in terms of metal replacement, improved and extended product performance or enhanced safety benefits. Beyond its engineering polymers, DuPont will use K-2007 to introduce a variety of modifiers including Biomax® Strong, Entira™ Antistat polymeric antistatic agents, Elvaloy® AC masterbatch carrier resins and ABS modifiers, silane functionalized Elvaloy® AC ethylene acrylate copolymers, innovations in rigid PVC modification, novel maleic-anhydride copolymers for PA, wire & cable and natural fiber composites. Product innovations will also be presented by the company’s titanium dioxide and performance elastomers businesses.

The DuPont Engineering Polymers business manufactures and sells Crastin® PBT and Rynite® PET thermoplastic polyester resins, Delrin® acetal resins, Hytrel® thermoplastic polyester elastomers, DuPont™ ETPV engineering thermoplastic vulcanizates, Minlon® mineral reinforced nylon resins, Thermx® PCT polycyclohexylene dimethyl terephthalate, Tynex® filaments, Vespel® parts and shapes, Zenite® LCP liquid crystal polymers, Zytel® nylon resins and Zytel® HTN high-performance polyamides. These products serve global markets in the aerospace, appliance, automotive, consumer, electrical, electronic, industrial, sporting goods and many other diversified industries.
