PANOX® - the oxidized fiber for textile applications
PANOX® is the industry standard when it comes to fire-retardant textile fibers. As an oxidized, thermally stabilized polyacrylonitrile (PAN) fiber that will not burn, melt, soften or drip, PANOX® is ideal for processing into yarns, woven fabrics, nonwovens and felts.
Applications:
Thanks to a high LOI (Limiting Oxygen Index) value, PANOX® is ideally suited for heat resistant, thermal and acoustic insulation and technical textiles. Typical applications are fire blocking fabrics for seating in aircraft, trains, busses and cars, or protective clothing for fire fighters, armed forces and police personnel, racing drivers and steelworkers.
PANOX® fibers are also used as an asbestos replacing additive in friction linings of automotive disc and drum brakes, as insulation material, industrial packings and gaskets.
Some of the largest applications of PANOX® are its uses as a precursor material in the manufacture of carbon/carbon aircraft brake discs, and in fire blocking felts for motor vehicles.
Specific applications:
- Bellows
- Ceramic brakes and clutches
- Fabrics for C/C clutches and transmissions
- Fireblocker fabrics for aircraft seats
- Flame-resistant mattresses
- Friction linings and brake pads
- Nonwovens for insulation of bonnet and transmission tunnel
- Optical effects in thermoplastic compounds
- Preforms and SMC for car body components
- Protective apparel
- Reinforcing cement-bound products
- Thermoplastic and thermosetting applications and technologies
- Welding blankets
- Woven fabrics and nonwovens used in buildings
