Chopped Fiber
Tenax™ Chopped Fibers are suitable for low- and high-temperature thermoplastic compounding processes and master batch pre-blends. Available in lengths from 3 mm to 25 mm, the fibers provide increased mechanical strength with weight reductions. Tenax™ Chopped Fibers enhance the electrical properties for ESD or full conductive applications, including for adhesives, resin systems, coatings, and specialty paper.
Tenax™ C-Series Chopped Fibers
Pillared-shaped types, featuring a bundled structure in compliance with the cut length.
Tenax™ P-Series Chopped Fibers
Rice-shaped types, manufactured from filament yarn cut in 3 mm lengths, with a unique pellet shape for improved feeding in manufacturing processes.
Both the C-Series and P-Series provide superior dispersion in compounds and are ideal for manufacturing using automatic feeding operations, including volumetric, gravimetric, vibrating tray and screw feeding in thermoplastic compounding operations.
Tenax™ Chopped Fibers can be used for a wide range of applications, such as the gas diffusion layer in fuel cells, cement or concrete reinforcement, electromagnetic shielding, and other applications where enhanced chemical resistance is required.

Life-cycle assessment of Teijin carbon fiber products
The life-cycle assessment (LCA) allows for a calculation of the total carbon emissions from a carbon fiber product. Teijin’s LCA methodology has been certified by an independent third-party organization in accordance with ISO 14040 and ISO 14044 standards. Teijin also provides customers with reliable emission data on Teijin’s carbon fiber filaments to help them evaluate their own footprints. Teijin’s LCA is useful in identifying carbon hotspots in manufacturing processes and evaluating options for emissions reduction. Teijin regularly collaborates with customers to decrease the carbon footprint of our products.
