In the current era of industrial modernization, High Temperature Resistant Yarn has transitioned from a niche specialty material to a cornerstone of advanced engineering. The global market, valued at billions, is being driven by the urgent need for materials that can withstand extreme thermal environments while maintaining mechanical integrity. Unlike traditional glass fibers or synthetic polymers, basalt-based high-temperature yarns offer a unique intersection of 1450°C melting points and superior chemical stability.
The rapid expansion of the Electric Vehicle (EV) sector requires thermal runaway protection materials. High-temperature basalt yarns are now the preferred choice for battery enclosure fire barriers.
Global fire safety regulations (such as UL94 and Euroclass standards) are mandating the use of non-combustible mineral fibers in public infrastructure and high-rise construction.
As industries move toward carbon neutrality, the "green" profile of basalt fiber—extracted from volcanic rock with minimal chemical processing—provides a significant E-E-A-T advantage over carbon fiber.
The manufacturing process of high-temperature resistant yarn involves melting crushed basalt rock at temperatures exceeding 1500°C. The resulting molten material is extruded through platinum-rhodium bushings to create continuous filaments. China Beihai utilizes advanced single-component furnace technology to ensure the chemical homogeneity of every yarn spool, which is critical for applications in aerospace and petrochemical sectors.
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. As a leading enterprise in the domestic basalt fiber industry, we bridge the gap between raw material science and industrial application.

The industry is currently moving towards "Smart Fibers." Research is underway to integrate sensing technologies into high-temperature resistant yarns, allowing structures like bridges and aircraft wings to "report" their stress levels and thermal health in real-time.
Another major trend is Hybridization. By combining basalt yarn with carbon or aramid fibers, manufacturers are creating "best-of-both-worlds" composites that offer extreme heat resistance alongside ultra-high modulus. China Beihai is at the forefront of this technical roadmap, investing heavily in surface treatment (sizing) chemistry to improve fiber-to-resin bonding.
Basalt products provide diverse applications in house construction, specifically in fire-rated wall panels and floor reinforcements where steel would corrode or lose strength under heat.
Ideal for manufacturing aircraft wings, engine components, and spacecraft shell materials. The thermal protection systems utilize basalt yarn for its stability under atmospheric reentry conditions.
Used in brake pads, mufflers, and engine covers. Basalt fiber composites offer a 20-30% weight reduction compared to traditional aluminum components.
Unique corrosion resistance makes it essential for underground piping and storage tanks where acidic soils and high-temperature fluids are present.
Protects bridge abutments from vehicle collisions, fire, and natural environmental erosion. Basalt rebar is non-conductive and immune to chloride ion attack.
Unmatched performance in salt-water environments. Unlike steel, basalt yarn components do not rust, extending the life of marine structures by decades.
Our macro-level industry solutions focus on Life Cycle Cost Reduction. While the initial procurement cost of high-temperature resistant basalt yarn may be higher than E-glass, the total cost of ownership is significantly lower due to reduced maintenance, zero corrosion, and enhanced safety margins.
Our production lines are certified to international standards, ensuring that every batch of wholesale high-temperature yarn meets the rigorous requirements of our global partners. We hold multiple patents for basalt fiber extrusion and sizing chemistry.
Basalt Fiber: Sparking a Materials Revolution
As drones and intelligent robots redefine modern industry, the demand for "hardcore support" materials like basalt fiber is reaching an all-time high.
