Derived from 100% natural, consolidated volcanic basalt rock, our needled felt products exhibit high thermal performance, structural integrity, and chemical inertness under conditions that degrade glass fiber or ceramic equivalents.
Continuous operational capacity up to 750°C (1382°F), with momentary resistance peaks reaching 1000°C (1832°F). The structural crystallization maintains dimensional stability, precluding shrinkage or catastrophic degradation.
Unlike organic binders or synthetic composite insulations, Beihai's pure mechanical needling process involves zero toxic chemical binders. Upon initial exposure to intense heat, the material produces zero smoke, fumes, or volatile organic compounds (VOCs).
Exhibiting stellar resistance to high chemical concentrations, hydrofluoric acid excluded. The basalt silica-aluminous crystalline grid keeps its mechanical tensile strengths intact when exposed to continuous industrial acidic condensates.
The highly complex and uniform interlocking micro-mesh pattern of individual continuous fibers provides exceptional sound absorption. This makes it an ideal option for dual acoustic-thermal industrial housings and exhaust chambers.
Founded in 2015 and situated in the industrial manufacturing hub of Jiujiang, Jiangxi Province, China Beihai (Jiujiang Beihai Fiberglass Co., Ltd. & Beihai Basalt Fiber Group) stands as a prominent high-tech enterprise. We focus on the comprehensive research, development, synthesis, and large-scale manufacturing of high-performance continuous basalt fiber (CBF) and specialized basalt process equipment.
Our vertically integrated facility controls every stage of the production cycle: from the select quarrying of pure natural volcanic basalt rocks, passing through optimized electric melting furnace draw operations at 1450°C, to proprietary sizing applications and precision mechanical needling. This integration allows us to supply global markets with basalt fiber mats, cloth, roving, chopped strands, rebar, sleeves, and customized high-temperature insulation felts.
Basalt felt is engineered to solve modern performance limitations across structural, thermal, and chemical-heavy fields.
Our basalt products provide robust reinforcement in building construction. They offer non-corrosive, thermal isolation barriers, structural plaster reinforcement, and fireproof underlayments that exceed international building safety codes.
By implementing strict dimensional standards and advanced processing technologies, our materials are deployed in spacecraft shell systems, engine firewall blankets, and structural brackets to survive extreme vibrations and heat shifts.
Our solutions support automotive lightweighting trends. They are widely utilized in high-temperature exhaust silencers, engine compartment thermal shields, and EV lithium-ion battery containment covers to prevent thermal runaway propagation.
Continuous exposure to aggressive acids and salty marine atmospheres degrades traditional glass fiber and steel. Our basalt fiber offers a strong protective shield for subsea pipelines, offshore rigs, and chemical storage reservoirs.
Operating with the highest levels of vertical integration, Beihai's manufacturing site in Jiujiang represents the modern standard for Factory 4.0 in high-performance continuous basalt fiber production.
Our long-term R&D efforts focus on next-generation hybrid continuous weaving, advanced bio-compatible sizing, and intelligent thermal-barrier profiling. By refining micro-nozzle melting processes and using precision heating, we ensure consistent fiber diameters of 9 to 22 micrometers. This consistency minimizes structural weak spots and maintains excellent flexibility across all needled felt configurations.
Furthermore, our automated drawing processes use inline laser sensors to control sizing application and mechanical stitch densities. This level of control guarantees the consistent loft and density required for reliable aerospace and industrial engineering applications.
With an abundant supply of local high-quality volcanic basalt ore and secure access to energy grids, Beihai offers long-term price stability. We shield our global partners from market fluctuations, geopolitical supply shocks, and rising energy costs, ensuring a reliable supply for critical infrastructure programs.
Our basalt felt features a highly interlocking fiber structure, allowing it to withstand extreme thermal shock without structural cracks. It retains over 75% of its structural tensile capacity even after long exposure to 650°C.
