Basalt roving

Basalt roving
Basalt roving

Basalt roving is 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 +6800С. Temporarily it can work in up to 900 0С. 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.
