1″ Basalt Fiber

$88.35$603.12

Basalt Chopped Fibers can be mixed directly into polymers and concrete to increase tensile strength and reduce cracking and chipping. Available in 6lb & 50lb bags.

Basalt Fibers advantages:

  • Stronger than fiberglass in tensile strength
  • 27% better elastic modulus
  • UV immune
  • Non-conductive
  • Better impact resistance does not shatter like carbon fibers
  • Ten times better electrical insulator than fiberglass
  • Very resistant to aggressive liquids, acids, and alkalies
  • Lower heat transfer coefficient than e-glass and carbon with greater thermal insulation properties
  • Low coefficient of thermal expansion; approximately the same as concrete

How are Basalt Chopped Fibers made?

Qualified* basalt rocks are broken into small pieces, washed, then melted in 1,888-degree F furnaces. The melted rock is drawn down through special bushings to make fiber filaments. The fibers are then chopped into various sizes. Coatings are applied to make the fibers bond to concrete or resins. All-natural rock basalt fibers are safe, non-respirable and do not burn. *Not all basalt is equal! The basalt has to have the right combination of silicate minerals.

Perfect for mortar and concrete reinforcement applications; all decorative applications as countertops, fireplace surrounds.

Basalt Fiber has a similar chemical composition as regular glass fiber but Basalt Fiber has better strength characteristics, and unlike most glass fibers is highly resistant to acidic and salt attack and alkaline, making it a good option for concrete, bridge and shoreline structures.

Compared to carbon and aramid fiber, Basalt Fiber has the features of wider application temperature range -452° F to 1,200° F (-269° C to +650° C), higher compression strength and higher shear strength, radiation resistance and higher oxidation resistance
