Evonik has developed a new generation of
polyimide fibers for the rising demands of the industry. The new product, brand
named P84 HT, is distinguished by improved mechanical stability and flexibility
at continuously high operating temperatures.
The new polyimide fiber continues Evonik’s
three decades of tradition of developing and producing high-performance
polymer-based fibers for the hot gas filtration market at the Group’s
Lenzing/Schörfling sites in Austria.
High-tech
fibers with maximum filtration efficiency
With their unique multilobal cross-section
and the largest surface area available in the market, these high-tech fibers
from Evonik offer high filtration
efficiency.
Due to their excellent chemical and
physical properties, P84 HT high-performance fibers can be used in a wide
variety of applications. These range from filter media for high-temperature
filtration, through protective clothing and sealing materials for space
vehicles, to various high-temperature applications such as thermal insulation.
Another competitive differentiating factor
of P84 HT consists in the improved textile properties at high temperatures. The
new polyimide fiber from Evonik retains its flexibility better than other
materials, even at temperatures around 280°C.
As a result, it remains more stable in
applications with relatively high average temperatures and frequent temperature
spikes. A standardized bending test shows that the new P84 HT fiber has almost
twice the flexibility of standard materials.
P84 — The ultimate
solution in hot gas filtration
In hot gas filtration applications, for
example, the innovative P84 HT filter media retain significantly higher
permeability over their entire life cycle. Depending on the field of
application, this could reduce emission of fine dust, waste gases and sensibly
reduce the total cost of ownership of the plant.
Evonik is the leading global producer of
chemically resistant, thermally stable, and non-flammable polyimide fibers.
These are produced at its chemical production sites in Lenzing, and Schörfling
am Attersee, Austria.
