    Manufacture of the material with other physical and mechanical properties is accepted upon agreeing about with a consumer.




  • 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.
