  • Typical application:

    • Glass voluminized roving is used for manufacture of filled composites and friction articles, woven and nonwoven materials.
    • Voluminized glass fibers are widely used in such fields as air filtration, thermal insulation, manufacture of filtering fabrics.
    • Voluminized rovings substitute for asbestos in many fields.
    • Voluminization improves performance and adhesive characteristics, hygienic properties of synthetic fabrics.
    • Texturized and voluminized glass yarns can save greater amount of air than single yarns thus providing better insulating properties.
    • Fabrics of voluminized fibers are notable for high strength, low density and good insulating properties, thermal stability, low thermal conductivity, high speed of filtration, low shrinkage, problematic deformation.
