ZOLTEK Chopped Fiber

ZOLTEK PX35 Chopped Fiber

Designed with cleaner and more consistent flow rates in mind, ZOLTEK’s chopped fiber is produced to have a high bulk density value. Commonly compounded with general engineering thermoplastics (e.g., PC, Nylon, etc.) and high-temperature thermoplastic resins (e.g, PEEK, PEI, etc.), the resulting composite offers industry-leading high strength-to-weight and stiffness-to-weight ratios. ZOLTEK’s chopped fibers also distribute easily during compounding, thereby improving process and product performance. ZOLTEK PX35 Chopped Fibers are versatile and readily available in a pellet, flake, or stick form.

ZOLTEK’s newly-developed Type-95 chop fiber format is characterized by a series of industry-leading benefits that make it an ideal solution for a variety of unique applications. Its high bulk density values allow for cleaner and more consistent flow rates. This product maintains its integrity from the package, into, and through the hopper. It distributes easily during compounding, thus improving overall process and product performance.

ZOLTEK’s Type-95 chopped fiber also has excellent mechanical and electrical properties including high strength and modulus, low density, electrical conductivity, dimensional stability, low thermal expansion, and excellent friction/wear properties.
