DuPont Plunkett Awards winners show that fluoropolymers continue to enable cutting-edge solutions


Shanghai, China, April 14, 2014. Seventy-five years ago, DuPont scientist Dr. Roy Plunkett discovered one of the most valuable and versatile materials ever – polytetrafluoroethylene (PTFE), which is sold by DuPont under the Teflon® brand. PTFE was the world’s first fluoropolymer, and after all this time, the unique properties of fluoropolymers continue to enable innovators across many industries to deliver solutions to critical challenges.

The competition in the Asia Pacific region opened last year. On March 7, 2014, a panel of international judges formed by leading experts in the industry met in Shanghai to select the entries that best met the judging criteria of degree of innovation, sustainability impact, breadth of use and commercial significance. Around fifty entries were accepted to take part in the competition.

DuPont Chemicals & Fluoroproducts today announced the Asia Pacific regional winners of the DuPont Plunkett Awards to recognize the accomplishments of those who continue to find new and exciting applications for DuPont fluoropolymers. The winning companies were honoured at an awarding ceremony at the Sheraton Hotel in Hsinchu, Taiwan. Winning entries will be featured at www.plunkett.dupont.com.

1st Prize: Nafion® membranes applied into vanadium redox-flow battery (VRB) for energy storage solution

Dalian Rongke Power company, who won the 1st prize, have made significant investment to develop existing VRB (vanadium redox-flow battery) technology. VRB is the first priority for energy storage, particularly for the energy produced from solar and wind renewable energy to even out the power output. Energy produced from these sources varies by the minute/hour/day and a need existed to even out the power distribution otherwise these forms of renewable energy will remain more of a curiosity than a reliable source of power. The development and installation of 5-10 megawatt VRB storage systems is a huge step forward for the renewable energy sector. Expected lifetime of a VRB system is more than 15 years, a significantly longer life than most other batteries.

2nd Prize: PTFE fine powder tubes for heat exchanger

The 2nd prize went to Wallstein Thermal Technology (Beijing). It has developed an energy recovery system that overcomes the very significant corrosion problems experienced within the coal fired electricity generation industry. Traditionally the energy recovery systems, probably better known as heat exchangers, have been fabricated from metal with the result that corrosive gases produced attack the metal and reduce the life of the heat exchangers. Wallstein has developed a heat exchanger based on Teflon® PTFE, which can withstand the high temperatures and provide enhanced chemical resistance. The new heat exchangers can be used for both the process energy recovery and also prior to discharge of the waste gases. The market potential is huge.

3rd Prize: Thin Coating on Pressure Roll for Toner Fusing System in Printer and Copier

The 3rd prize winner, Nissei Electric Co Ltd., has developed a laser printer pressure roll utilizing new coating technology. The pressure and fuser rolls are the heart within a laser printer, and both the print performance and life expectancy are dependent on these components. The pressure roll is traditionally made using a foamed elastomer core body over which a fluoropolymer coating is applied and is relatively expensive. This new technology allows for lower cost production without losing the high performance required of this component. Laser printers are now being purchased for private use and the potential for lower cost will make laser printers more attractive to a wider market resulting in increased sales.
