ZOLTEK PX35 Chopped Fiber
Chopped carbon fiber is a widely preferred material used in injection and compression molding applications. The resulting product or components are remarkably durable, corrosion-resistant, and incomparably rigid. Examples include machine parts and gears susceptible to long runs with minimal wear and tear. Designed for specific applications requiring cleaner and more consistent flow rates, ZOLTEK’s signature line of chopped carbon fiber materials are produced to have a high bulk density value. Often compounded with general engineering thermoplastics (e.g., PC, Nylon, etc.) and high-temperature thermoplastic resins (e.g, PEEK, PEI, etc.), the resulting composite offers an industry-leading strength to weight ratio ideal for a variety of applications requiring a stronger and more rigid carbon fiber material. In addition, ZOLTEK’s line of chopped carbon fibers distribute easily during compounding and improve the process and product performance as a result. ZOLTEK PX35 Chopped Fibers are versatile and readily available in a pellet, flake, or stick form. Learn more about our collection of chopped fiber products below.
