Pyromex® Continuous Filament Tow

Pyromex® is a family of oxidized poly-[acrylonitrile] (PAN) fibers. These fibers have a Limiting Oxygen Index (L.O.I.) of between 50 - 60% oxygen, making Pyromex® much more flame resistant than many other organic fibers such as PBI® ( 41% ), Nomex® ( 30% ), or Kevlar® ( 28% ). For carbon/carbon applications, the low sodium content of these fibers may aid in processing and performance.
