DuPont is “Managing Corrosion with DuPont™ Teflon®” at Achema 2009

Seminar in conjunction with company exhibit

Stevenage, April 2009. DuPont is underlining its exhibit at Achema 2009, the global summit for the chemical process industry (Frankfurt, Germany, 11th-15th May 2009), by hosting a seminar entitled “Managing Corrosion with DuPont™ Teflon®”.

Covering applications from across the process industry, including the power and waste, oil and gas and chemical industries, the seminar will introduce the range of Teflon® products, including resins, coatings and films, available for high-purity manufacturing.

The seminar will be held on Tuesday 12th May 2009, from 13.00 until approximately 18.00 in room Fantasie 2 at the Frankfurt Congress Centre. Visitors to Achema 2009 interested in attending free-of-charge should pre-register with DuPont via by the end of April.

Equipment resistant to corrosion and leaching is used in the manufacture of highpurity chemicals and solvents. As will be reflected by the DuPont seminar and exhibit at Achema 2009 (Hall 9, Stand H37-H38), much of this equipment – whether process vessels, tubing, valves and pumps or storage containers – can be lined with Teflon® PFA HP or Teflon® PTFE to extend service life and reduce maintenance, whilst protecting product purity. For example, the new Elaflon PTFE universal hose, developed by Elaflex-Gummi Ehlers GmbH in partnership with ContiTech Schlauch GmbH, is produced with a seamlessly extruded and smooth lining made of Teflon® PTFE. Principal application areas for the new hose include the chemical processing, food and pharmaceutical industries. The PTFE grade used for the lining is graded by the American FDA as conforming to its USP Class VI. Moreover, because the PTFE lining is fully conductive, the hoses are also considered Atex conform and may be used in Ex-Zones 0 and 1.

Corrosion resistant AlWaFlon® pressure hoses and pipes, based on Teflon® PTFE, provide a new and trend-setting application for fluoropolymers. They are a development of Wallstein (Recklinghausen, Germany), who worked in close cooperation with DuPont and Fluortubing (Utrecht, the Netherlands). Typical applications include their use in heat exchangers exposed to highly contaminated flue gases from power and waste incineration plants. They are very durable with the consequence of long-term, low-maintenance operation. Thanks to their long-lasting resistance to internal pressure, low wall thicknesses can be specified which, in turn, can allow high degrees of efficiency. One of the first applications of AlWaFlon® is in the flue gas coolers for the 850-MW-rated Belchatów power plant in Poland. Upon its completion in 2010, the coolers will reduce the temperature of the flue gas from around 170 °C to 130 °C.

Further topics to be featured at the seminar, and on the DuPont Fluoropolymer Solutions stand, include lining laminates made of Teflon® PFA, high performance filters based on Teflon® PTFE membranes and functional coating solutions with Teflon®.

DuPont Fluoropolymer Solutions is a leading producer of fluoropolymer resins, additives, films, finishes and dispersions, PTFE (polytetrafluoroethylene), PFA (perfluoroalkoxy), FEP (fluorinated ethylene propylene), ETFE (ethylene-tetrafluoroethylene) and PVF (polivinylfluoride), marketed under the registered trademarks DuPont™ Teflon®, DuPont™ Tefzel®, DuPont™ Tedlar® and DuPont™ Zonyl®. Major markets for these fluoropolymer products include the automotive, chemical processing, semiconductor, oil exploration, chemical handling, data communication, aerospace, electronics, housewares, building and renewable energy industries. DuPont is a science-based products and services company.

Founded in 1802, DuPont puts science to work by creating sustainable solutions essential to a better, safer, healthier life for people everywhere. Operating in more than 70 countries, DuPont offers a wide range of innovative products and services for markets including agriculture and food; building and construction; communications; and transportation.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
