Evonik has developed a new generation of fibers
P84 – the ultimate solution in hot-gas filtration
The high tech fiber 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 a 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.
