Faserpulp

Faserpulp refers to a family of fibrous materials derived from cellulose pulp that are used as reinforcements in bio-based composites and paper products. The term denotes the combination of high aspect-ratio fibers with a pulp matrix, enabling improved strength and stiffness in applications demanding light weight.

Faserpulp fibers are produced by refining or fibrillating wood or non-wood pulps to create microfibrils or microfibers, which are then incorporated into polymer matrices or bonded to paper. The processing can involve mechanical refining, enzymatic pretreatment, or chemical fibrillation, and the final form ranges from loose fibers to sheet-like networks.

The resulting materials typically offer good tensile strength, stiffness, and low density, with potential biodegradability depending on the matrix. Moisture sensitivity and variability in fiber-matrix adhesion are considerations, and surface treatments can improve adhesion and compatibility with different polymers.

Applications include reinforcement in bioplastics, packaging films and boards, automotive interior panels, filtration media, and textile substrates. Faserpulp is often positioned as a more renewable alternative to conventional fibers in sectors seeking lower embodied energy and lighter-weight components.

Environmental and economic aspects depend on pulp sourcing, energy use, and end-of-life routes. Pulp from responsibly managed forests and life-cycle assessments help guide adoption. Ongoing research focuses on optimizing processing efficiency, fiber-matrix bonding, and compatibility with a broader range of polymers.
