Discover our primary range of continuous basalt fiber products, engineered for structural reinforcement and premium thermal stability.
As industries operate in higher temperature zones under stringent regulatory protocols, the transition from synthetic polymers and hazardous ceramic fibers to volcanic-based silicate materials is accelerating.
Basalt Needle Felt Fabric represents the apex of inorganic material science. Derived from extruded pure basalt rock through advanced high-temperature melt-spinning, these textiles offer unmatched chemical inertness, high dielectric strength, and long-term operating limits up to 820°C. By avoiding chemical resins, the mechanical interlocking realized during the needle-punching process guarantees zero outgassing, ensuring absolute process safety across aerospace, refining, and clean-room environments.
*Comparative metrics verified through extensive ASTM testing. Basalt continuous fiber yields significant improvements in structural tensile strength and basic durability compared to standard fiberglass composites.
Founded in 2015 and headquartered in Jiujiang, Jiangxi Province, China Beihai is a recognized high-tech enterprise dedicated to research, manufacturing, and international distribution.
We lead the domestic basalt fiber industry through comprehensive control over both specialized high-precision manufacturing equipment and the final end-user composites. Operating modern melting basins and customized spinning systems, we assure batch-to-batch consistency and mechanical properties that outperform conventional inorganic materials. By bridging raw materials extraction and state-of-the-art textile manufacturing, China Beihai acts as an integrated global partner for heavy infrastructure, energy sectors, and aerospace supply lines.
As governments implement decarbonization policies and restrict mineral dust exposure in manufacturing plants, basalt fiber has emerged as the premier green material.
Unlike ceramic or crystalline fibers, basalt continuous filament has a diameter larger than 9 microns, making it non-respirable according to WHO standards, minimizing workplace liabilities.
Basalt fabric production is a single-component thermal process. It requires no addition of chemical binders, significantly reducing carbon emissions during manufacturing.
Excellent performance against highly aggressive chemical exposure, presenting high durability and zero alkaline decay when buried in marine or concrete environments.
Basalt needle felt is created through mechanical entanglement. Extruded continuous fibers with diameters ranging between 9µm and 15µm are laid onto high-precision distribution belts and subjected to high-density barb-needle penetrations.
This pure mechanical compaction forms a complex 3D fiber skeleton, providing high compression recovery, dense micro-porosity, and thermal trapping capacities. The absence of organic sizing agents prevents outgassing or chemical degradation when subjected to direct thermal exposure, making it an excellent choice for insulation. We supply customized densities from 100kg/m³ to 220kg/m³ and standard thicknesses between 3mm and 25mm.

A: Basalt needle felt offers a superior operating threshold (~820°C) compared to standard E-glass (~600°C), while avoiding the occupational health risks associated with respirable ceramic fibers. Basalt maintains better mechanical integrity and exhibits lower acidic/alkaline decay when subjected to chemical exposure. Additionally, it features excellent vibration damping and acoustic insulation coefficients compared to glass fiber.
A: No, our standard basalt needle felt is compacted pure volcanic fiber. We achieve mechanical stability entirely through high-density barbed needle punching. This ensures the felt is completely non-combustible and will not outgas, emit toxic compounds, or lose thickness due to binder burn-off at high temperatures.
A: We configure structural density from 100 kg/m³ to 220 kg/m³ and standard thickness from 3mm to 25mm. We can also integrate high-performance surface modifications, including aluminum foil lamination, silicone coatings, and specialized structural glass scrim layers, depending on the dynamic mechanical requirements of your project.
A: Traditional steel rebar suffers from oxidation (rust) when exposed to chlorides, leading to internal concrete cracking and structural failure. BFRP rebar is naturally corrosion-proof, has a tensile strength four times greater than steel, and is only a quarter of the weight. This makes it an ideal alternative for bridge deck construction, marine seawalls, and chemical containment structures.
A: Yes, basalt fibers maintain excellent mechanical properties and flexibility at sub-zero and cryogenic temperatures (down to -260°C). This allows them to serve as thermal insulation for liquid gas piping, aerospace fuel systems, and marine liquefied gas tankers.
Our manufacturing plants operate under strict ISO, CE, and ASTM manufacturing guidelines to ensure consistent high-quality outputs.
