ZOLTEK Chopped

While maintaining many of the attractive properties of virgin chopped carbon fiber, ZOLTEK’s recycled chopped carbon fiber also provides cost-saving and sustainability benefits. ZOLTEK’s two forms of recycled chopped carbon fiber are characterized by high strength and modulus, low density, dimensional stability, and low thermal expansion. They are also electrically and thermally conductive making them ideal for compounding with general engineering thermoplastics (e.g., PC, Nylon, etc.) and high-temperature thermoplastic resins (e.g, PEEK, PEI, etc.).

It is worth noting that, while recycled fiber properties vary, leading R&D indicates that properties reduction of only 3-5% compared to virgin carbon fiber has been exhibited in reclaimed chopped and milled fibers used to make thermoplastic compounds such as bulk molding compound. ZOLTEK recycled chopped fiber is readily available in pellet, flake, or stick form.

ZOLTEK Recycled Chopped Carbon Fiber – Type 45 is characterized by high strength and modulus, low density, dimensional stability, and low thermal expansion. It is also electrically and thermally conductive.
