Basalt Fibres
category
Basalt fibres are produced by melting volcanic basalt rock at 1400 to 1500 degrees Celsius and drawing the melt through platinum bushing tips into continuous filaments of 9 to 20 micrometre diameter without chemical additives, yielding fibres with tensile strength of 3.0 to 4.8 gigapascals, elastic modulus of 79 to 93 gigapascals, and service temperature range from minus 260 to plus 700 degrees Celsius.
Role
Provides a naturally sourced single-material inorganic fibre with thermal, acoustic, chemical resistance, and mechanical properties intermediate between E-glass and S-glass at competitive cost, positioned as an environmentally advantaged alternative reinforcement fibre for construction composites, high-temperature insulation, and automotive applications where basalt rock abundance ensures reliable raw material supply.
