Product Introduction Basalt Fiber Material is an advanced inorganic composite derived
from natural volcanic basalt rock. Melted at 1,450-1,500°C and
drawn into continuous filaments, it offers exceptional mechanical
strength, thermal stability, and corrosion resistance. - Eco-Friendly: 100% natural, recyclable, and free of carcinogens
- Extreme Temperature Tolerance: Operates in -269°C to 800°C environments
- Chemical Resistance: Impervious to acids, alkalis, and solvents
- Lightweight: 20-30% lighter than fiberglass with equivalent strength
- Applications: Structural reinforcement, thermal insulation, automotive parts,
aerospace components, and fireproof textiles
Manufacturing Process - Raw Material Processing: Basalt rock is crushed and melted in a platinum-rhodium alloy
furnace at 1,450-1,500°C
- Fiber Drawing: Molten basalt is extruded through spinnerets to form 7-25 µm
diameter filaments
- Textile Production: Filaments are woven into unidirectional (UD), plain, twill, or
satin fabrics using precision looms
- Surface Treatment: Coated with sizing agents (e.g., silane) to enhance adhesion and
UV resistance
- Quality Control: ISO 9001-certified testing for tensile strength (3,800-4,800 MPa)
and thermal stability
Usage Precautions - Mechanical Handling: Avoid sharp tools or excessive bending to prevent fiber breakage
- Chemical Exposure: Resistant to most chemicals but avoid prolonged contact with
strong oxidizers (e.g., concentrated sulfuric acid)
- Thermal Management: Prevent rapid temperature shifts to avoid thermal shock cracking;
use in dry conditions
- Storage: Store in ventilated, dry areas; avoid folding under tension
