ZOLTEK OX Staple Fibers are oxidized / stabilized PAN fibers (OPAN) that are inherently fire resistant, thermally stable, exhibit excellent resistance to chemicals and solvents and are electrically nonconductive. Available in three denier sizes and various cut lengths, ZOLTEK OX staple fibers can be used at 100% levels or in fiber blends to produce the highest quality nonwoven felts and the finest spun yarns in the market today.
