Basalt roving is an untwisted bundle of basalt continuous filaments. In the manufacturing process it is treated with special binders (sizing) that provide proper adhesion with applied environment.

Basalt roving has superior technical characteristics comparing to glass fiber and E-glass fiber and can be used as substitute to them. Due to its comparatively low price it could be a good replacement for carbon and aramide fibers in some applications.

- filament diameter 13 – 20 microns
- titer 60 – 4800 tex
- tensile strength 30 – 50 Gs/tex
- density 2.8 g/cm³
- elongation 4.5 – 8 %
- sizing: different recipes available according to final application environment

The diameter of fiber was measured according to GOST 6943.2-79
Titer was measured according to GOST 6943.1-94
Tensile strength was measured according to GOST 6943.10-79

Basalt chopped fiber is continuous filament cut to predetermined lengths to suit a particular application. The appropriate sizing is also used while chopped roving is being produced. This makes chopped roving compatible with other materials with which it has to coexist in applied environments.

- filament diameter 13 – 20 microns
- length 5 – 100 mm, step 5 mm or 6 mm
- moisture 12% or less
- sizing: different recipes available according to final application environment
