Flax fibre powder is a naturally sourced material obtained from finely ground flax fibres. This filler is attracting growing interest as a bio-based functional filler in numerous industrial formulations. Thanks to its micronised fibrous structure, it imparts specific properties such as mechanical reinforcement, reduced density, and contributes to the sustainability of materials. We offer high-quality flax fibre powder produced through an efficient defibration, grinding and sieving process. This enables us to guarantee consistent particle size and purity, ensuring reproducible performance.
