Basalt roving is a bundle of continuous unidirectional complex basalt fibers. Roving has high natural strength, resistance to aggressive environments, long service life and excellent electrical insulation properties. In terms of its technical characteristics, basalt roving surpasses S-glass and E-glass in many respects, and is not much inferior to carbon. Basalt roving is extremely heat-resistant: the temperature range for long-term use is from –260°C to +680°C. It can withstand temperatures up to 1000 °C for a short time. The basalt fiber direct roving of our company adopts the new pool kiln wiredrawing and is direct ly formed by 2400 hole large bushing. The basalt fiber direct roving is of high tensile strength, high elastic modulus, good thermal endurance, chemical resistance and electrical insulating.That is the reason why direct roving is used for production of fabrics and geogrids, as well for production of pultruded profiles and rebar. |
