High Tensile Strength Basalt Fiber Yarn for Composite Filament Winding

Engineered from high purity continuous volcanic basalt filaments our premium Basalt Fiber Yarn offers exceptional thermal stability and mechanical strength for advanced technical textiles and structural composite manufacturing. Manufactured by twisting fine basalt microfilaments into a smooth flexible strand this versatile yarn operates continuously in extreme temperatures up to 700 degrees Celsius while delivering superior resistance to chemical corrosion ultraviolet exposure and acidic conditions. Highly compatible with silane sizing agent systems it ensures rapid resin impregnation and excellent cohesion making it the perfect raw material for weaving heat resistant fabrics manufacturing electrical insulation sleeves producing fireproof sewing threads and executing high precision filament winding processes.

  • Surface Treatment Silane Sizing
  • Processing Service Cutting
  • Breaking tenacity(N/tex) ≥0.35N/tex
