China Alkali Resistance E-Glass Basalt Fiber Direct Roving for Fire-resistant Composite Materials Products, Suppliers

Basalt Fiber Direct Roving is a high-performance continuous fiber material. It is produced by melting basalt rock at high temperatures and then drawing it into single filaments through a platinum-rhodium alloy bushing. These single filaments are immediately gathered into a parallel, untwisted bundle of multi-filament strands, without any intermediate steps like bundling or twisting.
