Product catalog summary

Overview: The document is a technical data sheet for Meltrock® Basalt Roving, a high-technology material used in various construction applications such as reinforced grids, bars, and technical fabrics. It is produced by melting basalt rock and forming it into complex yarns, which are then lubricated, dried, and assembled into roving.

Marking and Specifications: Basalt roving is marked by type (BR), monofilament diameter (µm), linear density (tex), type of sizing, and bobbin unwinding type (internal or external). An example marking is provided for clarity.

Applications: Basalt roving is used in reinforced grids for road construction, composite pipes, tanks, cables, and more due to its high strength, mechanical properties, thermal range, chemical resistance, low thermal conductivity, and electrical resistance.

Mechanical Properties: The nominal linear density ranges from 600 to 4800 tex with a tolerance of ±5%. Monofilament diameters are 10, 13, and 17 µm. The linear breaking load is between 600 - 750 mN/tex, tensile strength exceeds 3100 MPa, Young’s Modulus is over 80 GPa, and elongation at break is between 2.0-4.5%.

Physical-Chemical Properties: Made from basalt rock, the material has a density of 2800 kg/m3, moisture content below 1%, and can withstand temperatures from -250°C to +650°C, with a maximum temporary application temperature of 1050°C. Weight loss at ignition ranges from 0.2% to 2.0%.

Packing and Storage: Bobbins have an outside diameter of 180 mm, inside diameter of 76 mm, height of 250 mm, and weigh less than 10 kg. Each pallet holds 72 bobbins, with dimensions of 1200x800x900 mm. Storage should be in a dry warehouse with humidity not exceeding 80%, and transport should prevent moisture absorption.

Conclusion: Basalt roving is a stable, high-quality material suitable for various composite applications, offering significant advantages in strength and durability.
