Evonik celebrates 35 years of polyimide fiber chemistry at Techtextil 2019

In 1984, for the first time ever, it was possible to spin fibers from the high-performance plastic polyimide.

This innovation was embedded by Evonik in the brand name P84® which has stood for high-temperature-resistant fibers for demanding industrial applications ever since. The specialty chemicals company will be celebrating the anniversary at Techtextil, May 14 – 17, in Frankfurt am Main, Germany (booth B37, hall 4.2).

“P84 is an excellent high temperature filtration polymer which is able to attract customers in new markets even 35 years after its introduction,” says Jean-Marc Chassagne, the managing director of Evonik Fibres GmbH. “Over the years, we have consistently established the polyamide fiber chemistry made in Austria to a worldwide quality standard in various applications.”

Due to decades of experience in polymer design, Evonik has now developed a new generation of fibers which fulfill the increased demand of the industry. The new product convinces by its improved mechanical stability at permanent operating temperature. Evonik will be commercializing the new fiber soon.

P84® – the ultimate solution in hot-gas filtration

The high tech fiber of Evonik has a unique multi-lobal cross section which ensures the highest level of filtration efficiency. Because of its excellent physical and chemical properties, P84® high performance fibers are used in a variety of applications. The spectrum reaches from filter materials for high temperature filtration, protective clothing, sealing applications for spacecraft
to a number of other high temperature applications, e.g. insulating panels for thermal insulation.

In high temperature filtration processes filter materials made of P84® fibers maintain a higher permeability at constant pressure drop through the entire life cycle. This leads to lower dust emissions and minimized energy costs.

“For example, more than 150 cement kiln applications are using P84® based filter materials. The energy saving of these optimized filters reduce the CO2 emissions by approximately 60,000 metric tons per year,” says Dr. Stefano Santorsola, the business director for P84® fibers at Evonik.

Evonik is the worldwide leader of chemical resistant, thermostable and non-flammable polyimide fibers. They are produced on the chemical plant in Lenzing, Upper Austria and further processed and customized in the neighboring production plant in Schörfling am Attersee.
