Engineered directly from continuous volcanic rock extrusion. These highly structured fiber solutions provide unparalleled thermal insulation, low density, and extreme chemical resistance.
Continuous Basalt Fiber (CBF) represents a monumental paradigm shift in high-performance materials science. Derived from the direct extrusion of 100% natural, high-purity basalt volcanic rock heated to over 1450°C, this single-component inorganic material contains no synthetic additives. Our proprietary high-temperature basalt tapes exhibit critical physical properties that place them at the absolute peak of industrial thermal insulation, structural reinforcement, and chemical containment barriers.
Unlike standard silicate fiberglass, which degrades rapidly under thermal fluctuation and mechanical stress, or carbon fiber, which is susceptible to high oxidation temperatures and is electrical conducting, high-temperature basalt tape possesses a highly balanced composition. It acts as an absolute electrical non-conductor, boasts a wide operating temperature range from -260°C to 700°C (with surge thresholds exceeding 1000°C), and presents exceptional resistance to alkaline, acidic, and saline environments.
As modern infrastructure, aerospace systems, and heavy industrial operations demand materials with high information-gain reliability, China Beihai’s specialized basalt composites deliver structural resilience where traditional polymer and silicate fiber matrices catastrophically fail.
Founded in 2015 and strategically based in the Jiujiang industrial hub of Jiangxi Province, China Beihai is a high-tech enterprise entirely focused on the research, design, engineering, and global supply of high-performance continuous basalt fiber (CBF) and advanced continuous manufacturing equipment. We are recognized as an industry-leading domestic enterprise with comprehensive vertical integration—from the selection of specialized volcanic basalt quarries to high-volume precision yarn drawing and final component fabrication.
Through close collaborations with prestigious state universities and industrial materials research institutes, our engineering team has developed high-capacity electric-melting crucible systems and highly stabilized multi-nozzle drawing systems. This technological edge ensures that our basalt continuous rovings, thermal insulation sleeves, geogrid meshes, surfacing tissue mats, and custom heat-resistant tapes are synthesized to precise structural specifications. Choosing to work with China Beihai means securing an innovative partner committed to absolute product reproducibility, optimized custom pricing, and multi-sector regulatory compliance.
What sets China Beihai apart is our robust vertical capacity to deliver advanced basalt matrices engineered for the most rigorous structural environments globally.
At China Beihai Group, we specialize in the continuous output of specialized basalt fiber products including surfacing tissue mats, continuous rovings, twisted yarns, reinforcement rebars, high-temp insulation sleeves, and high-tensile basalt tapes. This allows us to supply complete system solutions rather than isolated materials.
We leverage advanced precision processing and surface-coating technologies. By applying custom silane coupling agents and advanced sizings, our basalt fibers achieve excellent compatibility with epoxy, vinyl ester, polyester, and asphalt matrices, boosting long-term shear strength.
Continuous basalt fiber is an entirely green, non-toxic, and highly sustainable material. Its carbon footprint is up to 80% lower than carbon fiber or specialized alloys. Extruded with zero chemical effluents, basalt is fully inert, safe to handle, and leaves zero toxic residues.

With intensifying global environmental policies, decarbonization goals, and aggressive infrastructure modernization across North America, the European Union, and the Asia-Pacific region, basalt fiber has moved from a specialized material to a mainstream industrial commodity.
In highly regulated industries such as automotive manufacturing and aerospace, modern engineering criteria demand materials that reduce overall weight without compromising structural safety under thermal stress. The emergence of high-temperature basalt tapes has provided a critical solution. Historically, engineers relied on asbestos or glass fibers—materials that are either highly carcinogenic or chemically unstable under prolonged thermal fatigue. High-temperature basalt tape provides a 100% bio-inert, non-toxic, and mechanically superior alternative. Market projections show a significant compounded annual growth rate (CAGR) for basalt-based geotextiles and thermal wraps as heavy industry searches for REACH and RoHS-compliant materials that can withstand dynamic friction, mechanical shear, and sudden thermal spikes.
China Beihai basalt products have been successfully deployed in multiple engineering sectors, proving high reliability in harsh environments.
At China Beihai, our basalt tape products are manufactured using highly audited protocols to guarantee structural safety, operational performance, and material tracing. We comply with major international testing standards, ensuring our products can be directly integrated into international infrastructure, defense, and high-reliability aerospace projects.
Our Quality Management System conforms to ISO 9001, providing strict tracing from raw basalt rock sourcing to final package inspection. Additionally, our basalt fiber matrices comply with ASTM, REACH, and EU RoHS standards. This guarantees that our composite materials contain no dangerous substances, zero heavy metals, and generate no volatile organic compounds (VOCs) under high-temperature environments. Our local distributors across Europe, North America, and Southeast Asia ensure that your custom shipments receive local customs clearing support, engineering documentation, and fast technical service.
As high-temperature engineering challenges grow, China Beihai continues to innovate. Below is our technology development plan for next-generation basalt composites.
Development of hybrid weaving techniques combining continuous basalt yarn with high-modulus carbon fibers. This creates a cost-effective, high-toughness, and highly flame-retardant composite tape for structural wrapping in seismic zones.
Integration of nanostructured ceramic and carbon nanotube coatings. This enhancement raises the continuous thermal resistance of our basalt tapes to 900°C, and increases surface resistance to aggressive chemical solvents.
Researching basalt tapes with integrated piezo-resistive sensor filaments. These smart materials will monitor their own mechanical degradation and provide real-time structural health monitoring (SHM) for aerospace, bridge structures, and high-pressure chemical lines.
Technical answers to key questions about physical properties, mechanical behavior, and chemical resistance.
Our high-temperature basalt tapes exhibit a stable continuous operating temperature range from -260°C (-436°F) to +700°C (+1292°F). Under sudden thermal surges or direct heat shock, they can maintain physical integrity up to 1000°C for short periods. This makes them ideal for engine components, furnaces, exhaust shielding, and fire barriers.
Compared to E-glass and standard fiberglass, basalt tape offers up to 30% higher tensile strength, significantly higher elastic modulus, and superior chemical resistance to acids, alkalis, and moisture. Additionally, basalt has a higher operating limit (+700°C vs +480°C) and generates zero toxic off-gassing during thermal exposure.
Continuous basalt fiber is naturally resistant to alkaline solutions. Traditional glass fibers degrade quickly in the high-pH environment of wet concrete. Our basalt fibers maintain their mechanical properties, making them highly effective for concrete reinforcement, marine structures, and geogrids.
Yes. As a primary manufacturer, China Beihai can customize widths, thicknesses, and weave patterns (such as plain, twill, or satin). We also offer customized coatings—including vermiculite, PTFE, silicone, and specialized silane sizing—to optimize compatibility with different resin matrices.
No. Basalt fibers have a typical diameter range of 9 to 22 microns, well above the respirable threshold of 3 microns. While standard protective equipment (gloves and dust masks) is recommended when handling any industrial fiber, basalt tape does not cause the severe skin irritation associated with fiberglass and is free of asbestos-like health risks.
