China High-Performance Basalt Fiber Board Products, Suppliers

Basalt fiber board is a composite material plate reinforced by basalt fibers, with high strength, corrosion resistance, high temperature resistance and other characteristics, widely used in construction, transportation, energy and other areas

Product Description

Product Introduction
Basalt Fiber Board Introduction
Basalt fiber board is a high-performance material categorized into two primary types: Solid Boards and Sandwich Panels.
Solid panels are engineered from continuous basalt fibers through precision cutting, carding, and needling. This process forms a dense, three-dimensional interlaced structure using basalt fiber needle felt, stabilized with a high-grade binder under high temperature and pressure.
Sandwich panels feature a composite structure consisting of thin solid basalt boards as the outer layers and spliced rock wool strips as the core material. These components are bonded under extreme thermal conditions to ensure structural integrity and insulation.
Core Product Features
🔥 Extreme Heat & Fire Resistance (Grade A1)

Melting point of 1500°C. Operates stably from 700°C to 1000°C. Non-combustible, smoke-free, and non-toxic under fire conditions.

💪 Superior Strength-to-Weight Ratio

Only 1/4 the weight of steel while offering tensile strength that outperforms traditional metals. A cost-effective alternative to carbon and glass fiber.

🧪 Natural Chemical Inertness

Resistant to acids, alkalis, and salt spray. Offers an exceptionally long service life in coastal, chemical, and underground environments.

🌿 100% Eco-Friendly & Sustainable

Derived from 100% natural basalt rock with zero VOC emissions. Fully recyclable and aligns with global ESG and green building standards.

📡 Electromagnetic Transparency

Natural electrical insulator that does not interfere with radio frequency (RF) signals, making it ideal for high-end electronic infrastructure.

Detailed Technical Features
  • Thermal Stability: Thermal expansion coefficient close to concrete, preventing cracking or delamination during temperature fluctuations.
  • Acoustic Insulation: High Noise Reduction Coefficient (NRC) effectively dampens industrial noise.
  • Hydrophobic: Naturally water-repellent, prevents moisture absorption and mildew growth.
  • Ease of Processing: Easy to cut, drill, and machine, reducing installation time and costs.
