In the arena of advanced material engineering, Braided Basalt Sleeves represent a paradigm shift in passive thermal protection and mechanical containment. Derived from volcanic basalt rock through a single-ingredient melting process at temperatures exceeding 1450°C, continuous basalt fiber (CBF) is an entirely natural, ecologically inert material that possesses an extraordinary combination of physical properties.
Unlike fiberglass, which degrades rapidly under high thermal loads, or carbon fiber, which is electrically conductive and highly susceptible to oxidation at elevated temperatures, basalt fiber maintains its structural integrity across a vast temperature spectrum ranging from -260°C to +700°C (with short-term exposure limits up to 980°C). The braiding process further enhances these inherent properties by creating a highly flexible, expandable tubular structure that conforms seamlessly to irregular geometries, hoses, wiring harnesses, and high-pressure piping.
Maintains high tensile strength and structural stability at continuous operating temperatures up to 700°C. Non-combustible and produces zero toxic fumes during thermal degradation.
Highly resistant to strong acids, alkalis, organic solvents, and moisture. Ideal for harsh chemical processing environments, marine applications, and underground infrastructure.
Boasts a tensile modulus significantly higher than E-glass, providing exceptional abrasion resistance, impact dampening, and burst protection for hydraulic lines.
A pioneering high-tech enterprise dedicated to the research, development, and mass production of continuous basalt fiber and its downstream composite products.

Developing proprietary chemical sizing agents that optimize the interfacial bonding between basalt fibers and various polymer matrices (epoxy, vinyl ester, thermoplastic resins), maximizing mechanical load transfer.
Integrating aramid, carbon, and stainless steel wires into basalt braids to create multi-functional hybrid sleeves. These hybrids offer tailored electrical conductivity, enhanced impact resistance, and extreme cut protection.
Incorporating fiber-optic and conductive micro-filaments directly into the braided basalt structure to allow real-time structural health monitoring, thermal profiling, and leakage detection in high-pressure piping networks.
From deep-sea marine engineering to outer space exploration, basalt fiber composites are solving the world's toughest material challenges.
Basalt rebar, geogrids, and chopped fibers provide non-corrosive, high-tensile reinforcement for concrete structures, bridges, and highways, dramatically reducing maintenance overhead.
Lightweight basalt fiber composites are utilized in aircraft cabin interiors, cargo liners, and structural fairings, offering excellent flame retardancy and vibration dampening properties.
Engineered to withstand extreme thermal cycling, basalt fibers are integrated into spacecraft thermal protection systems, engine insulation blankets, and exhaust nozzle shields.
Adding basalt chopped strands to concrete mixes increases flexural strength, prevents micro-cracking, and provides superior resistance to chemical attack in marine and industrial flooring.
Ideal for lightweight structural components, exhaust system thermal wraps, and battery enclosure fire barriers in electric vehicles, preventing thermal runaway propagation.
Basalt composite jackets wrap concrete bridge piers to shield them from marine corrosion, freeze-thaw cycles, high-impact vessel collisions, and environmental degradation.
Highly acid- and alkali-resistant basalt piping and braided sleeves protect high-pressure chemical transfer lines from external corrosion and internal chemical wear.
Impervious to saltwater corrosion, basalt fiber laminates and sleeves are widely used in ship hulls, offshore drilling platform piping, and underwater structural reinforcement.
At our Jiujiang manufacturing base, we have integrated advanced automation and digital twin technologies to optimize every stage of basalt fiber synthesis.
