ZOLTEK OX

ZOLTEK has produced our oxidized PAN fiber, ZOLTEK OX for over 20 years. This level of experience, innovation, and expertise, has allowed ZOLTEK to fine-tune our process and become the largest oxidized PAN fiber producer in the world.

ZOLTEK in inherently flame resistant, making it an effective heat-blocking and fire barrier material. It outperforms all other organic flame resistant fibers in terms of limiting oxygen index and does so at a very competitive price. ZOLTEK OX textile products retain their appearance, have a soft hand and retain their textile characteristics, even after open flame exposure. Besides not burning, melting or dripping, ZOLTEK OX fibers will not shrink and they self-extinguish, when exposed to flame.

One of the largest benefits of ZOLTEK OX products are their versatility. ZOLTEK OX is available for all forms of textile processing including: needle punching, stitch-bonding, hydroentangling, thermal bonding, chemical bonding, air-laying, wet-laying, ring spinning, stretch-breaking, weaving, knitting and braiding. End uses include aircraft brake performs, transportation heat and flame blocking layers, thermal, acoustical and vibration insulation liners, flame resistant apparel, intumescent mesh and as raw materials for carbonized and graphitized yarns, fabrics and felts.

Produced from 100% ZOLTEK OX tow, ZOLTEK OX yarns are also at the foundation of ZOLTEK’s OX fabrics and felts. Because ZOLTEK OX yarns are inherently fire resistant, thermally stable, electrically nonconductive and exhibit excellent resistance to chemicals and solvents, there is no better yarn choice on the market. ZOLTEK OX stretch-broken yarns can be knit or woven and are often used in weaving and braiding applications for welding or mechanical packing end uses.
