Hall 9, Stand C13
At Achema 2012, DuPont representatives demonstrated how DuPont™ Kalrez® perfluoroelastomer parts and DuPont™ Vespel® CR-6100 parts enable chemical processors to sustainably improve their system efficiency, reliability and safety while reducing system cost. DuPont works together with customers to achieve optimum sealing solutions and durable wear solutions for very demanding chemical and hydrocarbon processing, and food and pharmaceutical applications.

“By using Kalrez® seals and Vespel® CR-6100 wear parts, process and rotating equipment, engineers can meet requirements for greater safety, reliability and productivity in their processes. These products can help increase MTBR (mean time between repairs) and reduce total system cost when used in a wide range of chemical processing industry equipment,” said Cedric Triquet, European Segment Lead, Kalrez® parts.

Savings in total system costs

DuPont™ Kalrez® perfluoroelastomer parts such as O-rings, gaskets, valve seats and diaphragms can withstand aggressive chemicals and maintain tight seals over a very wide temperature range. DuPont representatives provided case history examples from several global chemical companies and high-tech process pump manufacturers supporting the ability of Kalrez® seals to save from 10% to 200% in total system running costs in chemical, pharmaceutical and petrochemical processes. Data on file showed that seal lifetimes of O-rings in an aggressive chemical process were about six months for non-perfluoroelastomer O-rings and about three years for Kalrez®, leading to savings of 98% in cost of O-ring seals, installation, downtime and loss of productivity.

DuPont™ Vespel® CR-6100 wear parts and Kalrez® seals can help increase process system reliability, safety and productivity.

For the broadest possible chemical resistance, engineers turn to Kalrez® Spectrum™ 6375 parts because they can withstand most aggressive chemical families including acids, amines, bases, aldehydes, ethylene oxide, hot water and steam at service temperatures up to 275 °C.

To meet stringent cleanliness requirements in United States Food and Drug Administration compliant food and pharmaceutical applications, specifiers can use Kalrez® 6221 or 6230 seals to help protect process purity. These Kalrez® seals combine exceptional cleanliness with near-universal chemical resistance and outstanding elastomeric properties.

Improving pump efficiency and reliability
DuPont™ Vespel® CR-6100 parts such as wear rings have a proven record of success in pumps and other equipment for the chemical and hydrocarbon processing industries, and can deliver substantial improvements in pump reliability and energy efficiency at significantly less cost than currently available alternatives. They combine outstanding chemical resistance with low wear, low friction and extreme toughness, enabling the parts to survive long duration run-dry conditions, cryogenic service from -253°C to 'non abrasive' high temperature service at +288°C.
Cryogenic to high temperature sealing

Vespel® parts are available in other grades developed for specific applications. Vespel® SP-21 valve seats maintain a highly effective seal at cryogenic temperatures from -163 °C in liquefied natural gas (LNG) to as low as -269 °C (4K) in helium, for example. Remarkably, the same material maintains a compliant seal without detectable phase transitions up to continuous use temperatures of +300 °C.

Compressor applications

The DuPont™ Vespel® SCP family offers a step change in the performance of compressor piston rings, packing rings and rider bands, versus traditional materials such as PEEK and PTFE. Vespel® SCP-50094 parts demonstrate exceptional un-lubricated limiting PV capability of 17.5MPa.m/s in continuous use temperatures up to 325 °C, with compressive strength comparable to carbon steel. Vespel® SCP-5050 offers similar high performance with a coefficient of thermal expansion in the same range as stainless steel. The Vespel® product family includes grades for use in wet, dry and bone dry gases both lubricated and un-lubricated.

Vespel® CR-6100 parts also provide high temperature capability and outstanding chemical resistance in halogens and other difficult gases, making them suitable for compressor valve plate applications. High fatigue resistance, excellent flatness, and the strength and stiffness to survive high pressures coupled with a compliant sealing surface enable Vespel® CR-6100 parts to maintain a tight seal over a very wide temperature range.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
