Global Optimals’ basalt chopped fiber is a high‑performance reinforcement material with tensile strength ≥ 3000 MPa, fiber diameter 10‑20 µm and elastic modulus 93‑110 GPa. The fibers are produced by melting natural basalt rock at temperatures above 1500 °C and rapidly quenching the melt, which creates an amorphous glassy structure rich in alumina, iron, magnesium and calcium oxides. This micro‑structure gives the fibers exceptional thermal stability and chemical inertness, allowing them to retain mechanical properties from ‑260 °C to +982 °C and to resist aggressive environments such as strong alkalis and acids. Low moisture uptake (< 1 %) further enhances corrosion resistance, making the material suitable for replacing steel in construction reinforcement, for pultrusion profiles, geogrids, winding applications and aerospace composites where lightweight yet strong structures are required. In civil engineering, basalt fibers are often combined with epoxy resins to produce reinforced concrete meshes that improve seismic performance; in the automotive sector they are mixed with polyester matrices to fabricate lightweight body panels with high stiffness. When blended with carbon fiber, a synergistic effect is observed: the flexural modulus increases by about 15 % while tensile strength remains unchanged, a benefit valuable for aerospace components and high‑performance sporting goods. For optimal dispersion in composite blends, low‑speed mixers (≤ 500 rpm) are recommended and mixing time should not exceed 30 minutes to avoid fiber breakage. Storage conditions call for a dry, well‑ventilated area protected from direct sunlight and rapid temperature changes. Transportation is carried out in sealed bags together with complete technical documentation (TDS, SDS, COA). The fiber readily integrates with epoxy, polyester or vinyl matrices, resulting in composites with reduced impact sensitivity, lower thermal conductivity and improved acoustic damping, which expands its applicability to building panels, noise‑reduction structures and advanced engineering applications.

The basalt chopped fiber should be stored in a dry, well‑ventilated area, away from direct sunlight and heat sources. Keep the packaging sealed to prevent moisture ingress; regularly inspect bags or containers for integrity. Recommended storage temperature is ambient, typically between +5 °C and +30 °C, avoiding extreme temperature fluctuations. Shelf life is generally 12–24 months when stored under these conditions. During handling, wear protective gloves and safety glasses and avoid inhaling dust.
