Homopolymeric Polyacrylonitrile Fibre (PAN)

Homopolymeric Polyacrylonitrile Fibre (PAN)

The parent substances of PAN fibre are propene, ammonia and oxygen. The advantage of this fibre compared to copolymeric PAN fibres is its higher temperature resistance, improved chemical resistance and higher strength.
It is used mainly where polyester cannot be used owing to high moisture conditions. The fibre has a higher specific surface through its kidney-shaped fibre cross-section. It is frequently used as a mixed felt of PES/PAN.
