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 OX is 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 preforms, 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.

In the world of materials, ZOLTEK PX35 has emerged as the industrial carbon fiber –one that is both affordable and delivers a strength to weight performance equal to or better than many “aerospace’ grades. It is made from our abundant textile-based precursor and manufactured in a proprietary high-throughput process which results in affordable fiber without sacrificing strength or stiffness.

ZOLTEK PX35 is the low-cost commercial carbon fiber that has revolutionized the carbon fiber industry and paved the way for carbon fiber to break into a variety of new applications. Our sustainable pricing structure is independent of the volatile aerospace industry, and is designed to compete with other primary building materials.

Designed for use in the most extreme heat applications, ZOLTEK PX30 is an industry leading solution for challenges demanding very high temperature and very harsh chemical resistance properties. As a high purity and high-thermal performance material its various product forms are frequently used for fuel cells, carbon/carbon composites, energy storage battery, and many other specialty applications (outlined in the table below).

Derived from <<ZOLTEK OX products>> that undergo a proprietary high temperature batch carbonization process, ZOLTEK PX30 carbon fibers are PAN-based materials carbonised to >99%. Additionally, all ZOLTEK PX30 carbonized products are free of sizings, and the ZOLTEK in-house system ensures product quality and traceability from raw material through finished product.

It is estimated that more than 30% of produced carbon fiber ends up as waste at some point in its lifecycle. As innovators and leaders in the carbon fiber industry ZOLTEK sees this statistic as yet another opportunity to revolutionize the commercialization of carbon fiber.

While recycled carbon fiber modulus is basically the same as virgin carbon fiber, it also offers a 20 – 40% cost savings over virgin carbon fiber alternatives. Even with its 10-20% reduction in tensile strength, recycled carbon fiber remains one of the strongest of all commercial reinforcing fibers available today. Couple these benefits with the sustainability implications of giving new purpose to the 3,500 to 5,000 metric tons (>7.5 million to 11 million lb.) per year of recycled carbon fiber capacity and the potential of what was once considered “waste” becomes staggering.

ZOLTEK now offers Recycled Carbon Fiber forms as a part of our comprehensive product inventory. We believe this commitment to responsible production complements our mission to drive industries forward through stable pricing, supply availability, and advanced technology. Similar to the evolution of virgin carbon fiber as an available resource for commonplace applications, we believe recycled carbon fiber will be a large player in the next generation of commercial production around the globe.

As always, the ultimate goal is to connect our customers with a form of carbon fiber that is uniquely suited to their application. Although recycled carbon fiber may not yet be the ideal solution for every applications, we’re eager to partner with our customers to pursue the power of an even more sustainable carbon fiber in mainstream markets.
