Basalt roving is a bundle of continuous monodirectional complex basalt fibers. Roving possesses high natural strength, resistance to aggressive environments, long service life and excellent electric insulating properties. By its technical characteristics, Basalt roving surpasses S-glass and E-glass by many parameters, and is almost as good as carbon. Basalt roving is extremely heat resistant: long-use temperature range is 200-680 deg.С. Temporarily it can work in up to 900 deg.С. Roving is extremely hard: 8-9 on the Moh scale (for comparison diamond=10). Its specific strength is 2,5 times higher than alloy steel’s and 1,3 times higher than E-glass.

Typical basalt roving properties:

Monofilament diameter, microns 13 - 20
Linear density, tex 68 - 4800
Breaking load, cN/tex 50 - 55
Humidity, % less then 0.2
Reel weight, kg 5 - 15
Unwinding type internal/external

Technical advantages:

  • Light weight, high mechanical strength, corrosion and chemical resistance to alkali and other aggressive environments;
  • High resistance to freezing temperatures, heat resistance, moisture resistance;
  • Sound proof;
  • Ability to filtrate aggressive substances;
  • Unique chemical resistance;
  • High resistance to salt in sea water;
  • Resistance to UV radiation;
  • Dielectric properties;
  • Eco-friendly material
