Zoltek has developed a new product and sizing chemistry for use in vinyl ester resin systems. Introducing Zoltek’s PX35 Vinyl Ester Compatible Tow product. This new product, based on our proprietary sizing chemistry, exhibits excellent adhesion to and compatibility with vinyl ester resin systems. Most carbon fiber products are used to reinforce epoxy resin systems. Recently, the demand has grown for a product and sizing chemistry that can be used in vinyl ester resins whether cured thermally or via room temperature infusion. When compared to Zoltek’s standard carbon fiber product, PX35 Epoxy Compatible Tow, the new vinyl ester compatible product has significantly higher interlaminar shear strength (ILSS) and transverse flexural strength TFS, which both measure and indicate fiber to resin matrix compatibility and adhesion, as well as, composite performance. Zoltek’s PX35 Vinyl Ester Compatible Continuous Carbon Fiber is manufactured from a polyacrylonitrile (PAN) precursor fiber. The consistency in yield and mechanical properties that are provided by large filament count strands gives the user flexibility to design and manufacture composite materials.

ZOLTEK PX30 Woven Carbon Fabrics tailorability results from controlling the yield on rovings and yarns, and allows for a variety of finished composite thicknesses. The spun yarns have many surface fibrils that protrude in various directions at various lengths from the surface. This fiber loft contributes to high cross-ply tensile and interlaminar shear strengths for 2-D composite materials. Contour conformation without wrinkling is another advantage of spun yarn fabrics. ZOLTEK PX30 materials undergo high temperature carbonization process, involving a long temperature soak time, resulting in a very thermally stable and chemically pure fabric with low oxidation rate.

ZOLTEK’s Type-48 chopped fibers provide excellent mechanical and electrical properties for reinforcement in thermoplastic molding compounds requiring high strength and modulus, low density, electrical conductivity, dimensional stability, low thermal expansion and excellent friction/wear properties.

ZOLTEK OX yarns are spun yarns manufactured from ZOLTEK OX tow. ZOLTEK OX yarns are inherently fire resistant, thermally stable, electrically non-conductive and exhibit excellent resistance to chemicals and solvents. ZOLTEK OX yarns can be knit or woven and are used in high performance FR apparel, woven welding blankets, industrial fire-blocking layers, mechanical seals and gaskets, high temperature belting and can also be carbonized for use in carbon fiber composite end uses.

Produced from 100% ZOLTEK OX oxidized PAN fibers and later carbonized in our vacuum furnaces, ZOLTEK PX35 carbon felt is widely used. Current applications include insulation in high temperature furnaces, unique properties on our ZOLTEK PX35 carbon felts are invaluable when searching for solutions in complex thermal, corrosive, or conductive applications.

Like the continuous ZOLTEK OX tow from which it is made, ZOLTEK OX flock consists of oxidized and stabilized PAN fibers (OPAN) that are inherently fire resistant, thermally stable and resistant to chemicals and solvents. ZOLTEK OX flock is non-conductive and has a ~62% carbon content. ZOLTEK OX flock is designed for use in decorative thermoplastic and rubber compounding, friction materials and other end uses.

ZOLTEK PX30 carbon scrim is a plain leno weave fabric, produced from 100% ZOLTEK OX spun yarns, that undergo a high temperature, long carbonization soak process to obtain a high purity (>99% carbon) mesh material. The resultant chemically inert fabric exhibits superior thermal stability and a low oxidation rate. More specifically, our ZOLTEK PX30 high-purity carbon scrim fabric is a specialized product designed with an open weave construction which is ideal for applications requiring lightweight secondary reinforcement, such as that used in intumescent coating end uses. The scrim fabrics is usually supplied with an FR coated finish to provide easy handling and installation. In addition, our ZOLTEK PX30 High-Purity Carbon Scrim Fabric is manufactured to the same high quality and high standards as all of the ZOLTEK PX30 woven products.

ZOLTEK OX crimped 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 produce the highest quality nonwoven fabrics and the finest spun yarns on the market today.

ZOLTEK OX plain weave fabrics are produced from 100% 2-ply ZOLTEK OX yarn. These fabrics have high LOI%, good strength,can be laminated and have excellent cut and sew properties. Recommended uses include industrial flame and thermal insulation.

Produced from 100% ZOLTEK OX oxidized PAN fibers, needlepunched felts are for use as thermal/acoustical insulation in aerospace, automotive or general industrial high temperature applications. Valuable as a low cost - high performance fire or spark barrier.

ZOLTEK PX30 Low-Oxidation Knitted Carbon Fabric is high modulus fiber fabric made from spun yarn. The fabric has a jersey knit construction, which will conform to multiple curvatures. Thermal oxidative and dimensional stabilities are attained during heat treatment. Applications of ZOLTEK PX30 Knitted Fabric include thermal protection systems, such as, heat shields, rocket nozzles, and carbon/carbon brakes.

ZOLTEK’s Type-45 Recycled Chopped Fiber format has high strength and modulus, low density, electrical conductivity, dimensional stability and low thermal expansion.

ZOLTEK’s Type-65 Recycled Chopped Fiber format has high strength and modulus, low density, electrical conductivity, dimensional stability, low thermal expansion.
