Deploying continuous basalt fiber (CBF) technology to establish next-generation thermal containment, extreme-temperature resistance, and ultimate structural protection frameworks.
Founded in 2015 and situated in the industrial technology zone of Jiujiang, Jiangxi Province, China Beihai operates as an elite national high-tech enterprise dedicated to the comprehensive life cycle of high-performance continuous basalt fiber production and manufacturing equipment engineering.
Our company holds an authoritative position in the domestic basalt fiber spectrum, directing industry-level innovations in deep-melt basalt extrusion, advanced mineral batching, and extreme-durability applications. By uniting dynamic engineering capabilities with state-of-the-art facilities, China Beihai serves as a bedrock partner for worldwide construction, aerospace, petrochemical, and power transmission enterprises requiring rock-solid thermal barrier materials.
We specialize in producing high-temperature basalt solutions: needled mats, continuous rovings, twisted yarns, chopped strands, structural non-conductive rebars, thermal protective sleeves, and high-tensile structural fabric matrices.
We manufacture precision-engineered basalt geo-grids and asphalt reinforcing layers, extending infrastructure lifetimes, avoiding reflective cracking, and introducing unparalleled eco-friendly mineral durability.
Partnering with China Beihai translates to integrating 100% natural, recyclable, inorganic mineral composite systems into your supply chain. We guarantee extreme thermal parameters, structural longevity, and global compliance.
Modern heavy industries require thermal barrier materials that exceed conventional limits. Traditional ceramic and glass fibers face strict ecological regulations and structural decay under high mechanical loads. High-Temperature Basalt Insulation Boards represent the pinnacle of modern material science. They are synthesized directly from volcanic basalt rock, presenting a zero-resin or low-binder structural envelope capable of withstanding constant operating temperatures up to 980°C (1800°F).
For global procurement offices, structural integrity is determined by precise engineering metrics. Below are the verified technical parameters defining China Beihai's continuous basalt fiber products:
| Performance Properties | Basalt Mineral Fiber (CBF) | E-Glass Fiber | Ceramic Fiber |
|---|---|---|---|
| Operating Temperature Threshold | -260°C to +980°C | -60°C to +650°C | up to +1250°C (Unstable) |
| Thermal Conductivity at 400°C | 0.035 - 0.042 W/(m·K) | 0.082 W/(m·K) | 0.090 W/(m·K) |
| Tensile Strength Retention (After 100h) | > 82% at 500°C | < 35% at 500°C | Decomposes into respirable dust |
| Alkali & Acid Resilience (pH 1-14) | Outstanding (95% retention) | Poor (Degrades in concrete) | Moderate |
| Eco-Toxicity & Health Hazards | Zero (100% Inert Rock) | Minor irritation | Classified Class 2B Carcinogen |
From submarine hulls to deep-space launch pads, basalt continuous fibers satisfy extreme stress thresholds across the globe.
Utilized for internal non-combustible partition walls, high-rise thermal core isolation, and lightweight fireproofing doors.
Ideal for structural aircraft skin insulation, wing root heat insulation shields, and cabin firewall barriers.
Integrated into dynamic thermal protection wraps, launch vehicle exhaust housings, and cryo-insulation systems.
Alkali-resistant continuous fiber reinforcement meshes eliminate road and structural concrete micro-cracking issues.
Exhaust insulation mufflers, engine firewall pads, and high-performance friction-clutch pad stabilizers.
High-strength continuous wrap composites protecting reinforced concrete bridge columns from sea water, salt, and impact.
Extreme chemical-resistant insulation overlays on pipeline systems, containing acids and volatile hydrocarbons.
Engine room firewall cladding, hull thermal barriers, and insulation elements entirely immune to marine corrosion.
Procurement directors and dynamic engineering consultancies around the globe depend on verifiable numbers to justify component specifications. Our manufacturing plant operates with rigorous, real-time performance inspection processes to meet extreme global standards.
When sourcing high-temperature insulation boards or continuous fiber composites, engineers should target four primary metrics:
"Transitioning structural building designs to basalt-reinforced matrices reduces overall structural dead-weight by up to 40% while raising fire classification thresholds to Class A1 Non-Combustible. In thermal engine configurations, our custom insulation solutions restrict outer casing temperatures to within human-touch safety envelopes (< 60°C), minimizing active ventilation system loads."

Conventional high-temperature insulation boards often rely on organic resins that degrade or produce smoke under high heat. Our research program focuses on integrating mineral-based silica nanotech binders into the basalt fiber matrix. This ensures zero decomposition up to 1000°C, offering smoke-free performance ideal for cleanrooms, laboratory equipment, and passenger ships.
By infusing continuous basalt needle-bonded mats with silica aerogels, we are developing thin insulation panels with exceptionally low thermal conductivity: < 0.018 W/(m·K). This technology allows high-performance thermal insulation in spaces with severe thickness constraints, such as electric vehicle battery compartments and compact engine compartments.
Urban electrification, high-voltage networks, and MRI scanning bays require structural concrete components that are completely non-magnetic and highly insulated. The development of custom-sized alkali-resistant basalt rebar systems provides critical structural support without electromagnetic interference. This solution delivers corrosion-free performance, eliminating maintenance needs for decades.
Because basalt is manufactured from 100% natural volcanic basalt stone, all production scraps, leftover fiber mats, and decommissioned structures can be remelted and reshaped into new high-strength products. This closed-loop life cycle offers an exceptionally low carbon footprint compared to carbon fibers, supporting green building certification systems like LEED and BREEAM.

As drones monitor rugged terrain and industrial robots carry out repetitive tasks on automated factory floors, modern machinery requires durable protective materials. High-performance, continuous basalt fiber acts as a strong, protective shield. It delivers crucial safety, flame resistance, and thermal isolation to support structural stability in the most demanding conditions.
