Basalt Roving Yarn

Direct Roving for Continuous Processing

Many reinforcement methods use basalt roving as a direct input, and the product range offered includes basalt roving up to 2400 Tex. These rovings are primarily manufactured in 20 kg spools, according to packaging information. Pultrusion, tube wrapping, and the manufacturing of chopped basalt fibres are among the listed uses. The roving shape offers a straightforward way to include continuous basalt fibres into production for clients utilising composite profiles or other reinforcement techniques.

The papers provided expressly identify two test report references for 800 Tex and 2400 Tex basalt rovings. The fibre diameter range for basalt is 6–13 μm according to general criteria, and the roving information is generally displayed in Tex and spool formats rather than a fixed structure.

For Pultrusion, Tube Wrapping and Chopped Fiber

The processing method is the reason roving yarn is preferred over twisted yarn. Basalt roving can be turned into chopped basalt fibres or used as reinforcement for pultrusion and winding tubes. Additionally, the 20 kg spool format offers a defined packing unit for controlled material input and industrial handling.

General technical information regarding basalt fibres describes their high strength, high modulus of elasticity, electrical insulation, corrosion resistance, and high temperature resistance. A separate set of specifications calls for a minimum elongation at break of 2.2%, a minimum tensile strength of 2000 MPa, a minimum fracture toughness of 5 cN/dtex, and a minimum modulus of elasticity of 90 GPa.The precise product and testing foundation should match these values.
