EAS offers both fine basalt fiber yarn, basalt direct roving as well as texturized basalt roving or yarn.
Basalt yarn is high performanced mineral fiber among carbon fiber, glass fiber, aramid fiber. The basalt fiber textiles will be popular used in the composite reinforcement, construction, thermal insulation area.
Basalt Roving:
Assembled basalt roving (800-4800tex) consists of several basalt fiber filament strands, formed at the facility for the production of continuous basalt fiber and then assembled together.
Direct basalt roving (100-600tex) is direct single filament strands, formed at the facility for the production continuous basalt fiber
