DuPont™ Kalrez® AeroSeal™ 7800 perfluoroelastomer parts help minimizing corrosion of titanium and stainless steel for longer part life. DuPont™ Vespel® ASB-0670 parts for fan blade wear strips provide significantly longer wear life versus incumbent coatings.
DuPont™ Kalrez® and Vespel® high performance parts are used in demanding aerospace and aircraft engines.
DuPont™ Kalrez® and DuPont™ Vespel® high performance parts have provided innovative solutions to complex aerospace sealing, wear and friction challenges at high temperatures for over 45 years. Kalrez® perfluoroelastomer parts are used as oil seals in turbine and jet engines and air delivery systems. Vespel® parts offer very high temperature capability, wear resistance, and low friction to effectively replace metallic materials.
“DuPont tests with Kalrez® AeroSeal™ 7800 parts demonstrate low corrosion in titanium and steel for 1000 hours @ 250 °C with excellent compression set resistance, and offer a maximum service temperature of 325 °C”, says Mark Schmeckpeper, global aerospace marketing manager DuPont™ Kalrez® and Vespel®. And he continues: “Our equally new Vespel® ASB-0670 parts perform in very demanding conditions. They can be found in blade wear strips, where friction and load create high stress. They provide improved wear resistance and a low coefficient of friction compared to other polyimides over a wide range of temperatures. In DuPont wear tests, that have been confirmed by customer tests, Vespel® ASB-0670 parts have shown exceptional performance.”
Polyimides Improve Wear Resistance, Reduce Weight
Vespel® SCP parts, which debuted at Paris Air Show in 2011, provide improved wear resistance at elevated temperatures and a low coefficient of friction compared to earlier polyimides. In applications where non-metallic materials have never been widely used, engineers are relying on the high-temperature capabilities and wear resistance of Vespel® SCP parts to replace metal, thus saving weight and improving fuel effiency. “SCP parts are a key reason why we’re gaining more and more approvals for use in aircraft systems in wear applications, including bumpers, wear pads, bushings, seals and shrouds,” said Schmeckpeper. Vespel® SCP parts typically weigh 75 to 80 percent less than stainless steel and substantially less than aluminum or titanium components.
DuPont™ Kalrez® and Vespel® high-performance parts provide innovative solutions to aerospace designers and specifiers when complex sealing, wear or friction difficulties are encountered.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
