Unlike synthetic compounds, continuous basalt fibers are manufactured through single-ingredient melting of high-purity volcanic basalt rock. Extracted from deep quarry formations, the raw material is processed at temperatures reaching 1450°C. This single-material extrusion process produces pure mineral filaments that avoid the degradation associated with chemical blending.
When braided into dense **Basalt Fiber Sleeves** and high-tensile **Wrapping Tapes**, the resulting materials provide an exceptional thermal shield. These basalt products can endure continuous exposures up to 700°C (with peak resistance spikes up to 900°C) without losing their dimensional stability or structural layout.
A detailed engineering evaluation highlighting basalt's performance advantages across critical parameters like thermal threshold and cost efficiency.

Our premium basalt fiber sleeves and heat-shielding tapes operate within a temperature range of -260°C to +700°C. Under dry conditions, they maintain structural integrity and tensile strength, resisting thermal shock and spikes up to 900°C.
Continuous basalt fiber exhibits exceptional chemical resistance compared to silica and E-glass. When exposed to 2M HCl acid solutions for 3 hours, our basalt fiber retains over 75% of its structural strength, while E-glass exhibits rapid physical degradation.
We supply a wide range of custom braiding profiles. Our basalt sleeves are available in internal diameters (ID) from 6mm up to 150mm, with wall thicknesses ranging from 0.5mm to 5.0mm. Basalt insulation tapes are supplied in widths of 10mm to 200mm, featuring either plain, twill, or drop-warp (ladder tape) configurations.
Yes. We offer custom chemical sizing formulations, including silane and specialized coupling agents, to ensure compatibility with epoxy, phenolic, polyester, and vinyl ester resins, maximizing interface adhesion in composite applications.
Every shipment is accompanied by comprehensive quality control documentation, including Mill Test Certificates, ASTM compliance reports, and CE/ISO declarations. We maintain strict batch traceability from raw material melting to final packaging.
For standard specifications, our MOQ starts at 500 meters. Custom ID braiding, unique weave patterns, or specific chemical sizing coatings typically require a minimum run of 1,000 meters. Standard production lead time is 15 to 20 business days.
Basalt fiber is 100% natural, manufactured strictly from quarried basalt rock with no chemical additives, pigments, or synthetic fillers. Processing basalt rock requires significantly less energy and generates fewer carbon emissions than carbon or glass fiber manufacturing.
Yes. Basalt fiber is an excellent electrical insulator with a high dielectric strength and low dissipation factor, making it ideal for electrical cables, wiring systems, and underground utility conduits.
We utilize laser-guided inspection systems on our braiding lines. This ensures diameter, wall thickness, and pick count values are monitored continuously, maintaining precision and batch-to-batch consistency.
Basalt filaments are smoother and less prone to breaking than fiberglass. The application of our custom protective coatings minimizes fiber shedding during handling and installation, reducing skin irritation for technicians.
