MIFIBRA S.L. is a young company settled in O Barco de Valdeorras (Ourense, Spain) dedicated to the manufacture of a new continuous mineral fiber based on slate waste.

This fiber has extremely good thermal, mechanical and chemical properties. Ours is the only fiber on its kind.

This project was started several years ago in a lab scale, and then we step up to a industrial scale, working together with theICG (Galician ceramic Institute) linked to University of Santiago de Compostela (USC).

We now run a stable production in a optimized unit with 50 t/year capacity.

Our primary products are the roving and the chopped fiber.Based on these, we manufacture product like pultrusion bars and profiles, fabrics for laminates of isolation panels, twisted yarn, etc.
