Construction glass fabrics are one of the types of glass fiber materials which are designated for production of glass reinforced plastics as a reinforcing material. Glass reinforced plastics on the basis of woven materials in comparison with glass plastics on the basis of non-woven materials have higher physical-mechanical properties and are used in production of critical parts and structures. Thanks to the fact that the given glass reinforced plastics have such properties as high impact strength, temperature resistance, high tensile strength, corrosion resistance, antimagnetic properties, locality of destruction of a damaged area, high dielectric properties make their application irreplaceable in all branches of industry, in production of car body parts, yachts, launches and their decorative elements; different structures of any kind of profiles; composite materials; chemical tanks, apparatus, pipe work and so on. Construction glass fabrics are made of aluminoborosilicate glass type “E” with different weaving structure, untreated or pre-impregnated for improved interaction with polyester, epoxy, formaldehyde, epoxy phenol and other types of resins. Among construction glass fabrics the enterprise also manufactures a wide range of roving glass fabrics. JSC “Polotsk-Steklovolokno” manufactures also hollow fiber and glass fabrics on its basis at the special technology. Non-woven materials and fabrics produced on the basis of hollow fiber are used as a reinforcing material in production of light-weight glass reinforced plastics, which are 20-30% lighter on retention of the same strength properties. JSC “Polotsk-Steklovolokno” also produces filtering fabrics and meshes made from E-glass. Filtering fabrics are intended for high-temperature filtering exhaust industrial gases at the temperature up to 300°C. Filtering meshes are used for filtering molten aluminium and its alloys.
