View DetailsIn high-temperature industrial design, engineering teams search for materials that balance high safety margins, long life cycles, and extreme resistance to thermal degradation. The Custom Basalt Fiber Needle Mat stands at the pinnacle of advanced inorganic materials engineering. Fabricated directly from molten volcanic rock, this non-woven mat is manufactured by passing continuous basalt fibers through a precise mechanical needling system. This interlocks the individual strands without the addition of chemical binders, resin additives, or organic sizing agents, ensuring completely smoke-free, eco-friendly operation even in direct flame-contact scenarios.
As standard fiberglass materials experience thermal breakdown at 500°C and ceramic fibers face heavy scrutiny due to airborne particulate health concerns, high-density basalt fiber needle mats emerge as the premier alternative. Delivering continuous operation thresholds up to 700°C (and structural integrity spikes exceeding 900°C), this volcanic fiber structure provides a rare synthesis of low thermal conductivity, high acoustic attenuation, extreme chemical inertness, and structural tensile strength.
The global demand for custom basalt needle mats has surged dramatically. This growth is fueled by stricter international emission standards, energy conservation mandates, and safety codes across industrial sectors. Major markets including North America, the European Union, and the Asia-Pacific region are accelerating the integration of basalt needle mats into multiple critical areas:
Founded in 2015 and strategically located in Jiujiang, Jiangxi Province, China Beihai is a premier high-tech enterprise dedicated to the research, development, production, and worldwide distribution of continuous basalt fiber products and specialized manufacturing machinery.

In global composite materials procurement, balancing costs, quality, and supply continuity is critical. China Beihai Group addresses these needs through our vertically integrated facility in Jiujiang, Jiangxi, delivering several core advantages:
Our close proximity to premium volcanic basalt rock quarries in China ensures strict control over chemical consistency. Selecting ore with stable levels of silica (SiO2), alumina (Al2O3), iron oxides (Fe2O3/FeO), and alkaline oxides (CaO/MgO) is essential for consistent melting behaviors, uniform mechanical needling, and reliable thermal profiles.
China Beihai operates high-efficiency, multi-nozzle platinum-rhodium alloy bushing draw systems. This advanced process produces continuous basalt filaments with precise fiber diameters (typically 9µm to 15µm), preventing brittle points and ensuring uniform mechanical needle density across all rolls.
Our production line allows custom tailoring to your exact structural specifications:
• Thickness range: 3mm to 25mm.

A basalt fiber needle mat is a non-woven, mechanically bonded insulation sheet manufactured from continuous basalt filaments. These fibers are laid down in a uniform web and interlocked using a specialized needling loom. Because the fibers interlock mechanically, the mat requires zero chemical resins, binders, or organic sizing agents, making it completely smoke-free and highly stable at high temperatures.
Our custom basalt fiber needle mat operates continuously at temperatures up to 700°C (1292°F). Under short-term peak thermal exposures, it maintains structural integrity at spikes exceeding 900°C (1652°F). It does not melt until temperatures surpass 1450°C, providing an exceptional safety margin compared to traditional glass fibers.
Basalt fiber offers superior thermal performance and acid/alkali resistance compared to standard E-glass, which typically degrades around 500°C. While refractory ceramic fibers (RCF) support higher temperatures, they are increasingly restricted due to health concerns over inhalable crystalline silica dust. Basalt needle mats provide a safer, eco-friendly alternative with excellent mechanical properties and no health hazards.
