Explore our top line-up of continuous basalt fiber products engineered for extreme thermal preservation, friction control, and mechanical reinforcement.
In modern thermodynamics, high-temperature operations mandate high insulation efficiency and extreme material stability. The global market is transitioning from glass fibers and synthetic polymers to natural, single-ingredient silicate materials. Continuous basalt fiber represents a major upgrade, offering mechanical strength, chemical resistance, and wide thermal survival windows from -269°C to +700°C (with excursions peaking at +980°C).
Information Gain Insight: Unlike standard E-Glass fiber, which degrades at 550°C and loses structural reliability in acid/alkali environments, basalt continuous fiber retains over 80% of its mechanical strength under chemical and thermal duress. This makes it crucial for complex deep-sea exploration, critical aerospace engines, and zero-emission automotive setups.
As leading custom insulation sleeve manufacturers, we focus on user intent. Industrial engineering procurement demands reliable performance under extreme friction and high temperatures. Traditional insulation sleeve products degrade due to thermal fatigue or chemical corrosive runoff, which ruins wires, hoses, and mechanical linkages. By using dense braided configurations made of continuous basalt fiber, we deliver dynamic, long-lasting insulation sleeves that lower maintenance costs and improve energy efficiency.
Founded in 2015 and located in Jiujiang, Jiangxi Province, China Beihai is a high-tech enterprise focusing on the research, development, production, and sales of high-performance basalt continuous fiber and its production equipment manufacturing.

How continuous basalt fiber products solve high-stress thermal and physical challenges across major industries.
We supply fireproof materials that isolate structural elements, providing fire resistance for modern buildings, tunnels, and public infrastructure.
In aviation, basalt fibers protect critical wire harnesses, electronics, and exhaust lines from high-heat and pressure environments.
Basalt sleeves serve as high-temperature thermal barriers for rocket thruster parts, external instrumentation, and vehicle atmospheric reentry systems.
Adding basalt fibers to concrete increases tensile capacity, reduces cracking, and improves corrosion resistance in coastal structures.
Basalt sleeves wrap manifolds and catalytic converters to manage engine heat, protect nearby sensors, and improve vehicle efficiency.
Basalt products shield bridge piers from vehicle impacts, fires, moisture, road salt, and harsh outdoor exposure.
The excellent chemical inertness of basalt sleeves helps protect pipe networks and fluid systems from corrosive chemical splashes and acid leaks.
Our salt-water resistant basalt wraps shield steam pipes and electrical systems on offshore platforms and marine vessels from high humidity and corrosion.
As industries pursue net-zero carbon goals, insulation sleeve design is moving toward smart, multi-layered, and ecological structures. China Beihai Group is leading research into three primary technical initiatives:
By blending high-purity continuous basalt filaments with polycrystalline alumina fibers, we are developing hybrid sleeves that can withstand continuous exposure up to 1100°C. This meets the thermal protection requirements of next-generation aircraft and rocket exhaust systems.
We are researching smart sleeves by braiding thin, flexible sensor wires directly into the basalt structure. This allows real-time thermal profiling and structural health monitoring along pipeline networks, helping prevent thermal runaway in chemical plants and battery assemblies.
Traditionally, sizing chemistry relies on synthetic chemical bases. We are developing organic, bio-based sizing agents that reduce emissions during high-temperature operations, ensuring our green volcanic basalt fibers remain clean throughout their entire life cycle.
China Beihai Group maintains strict quality management and supply-chain transparency to meet global engineering standards. We help clients navigate complex regional safety, environmental, and engineering codes:
