Description of the process

  • COVERING

This process consists of winding a sheet made of glass filament tape on an electrical conductor to provide insulation resistance. The tapes are often produced on narrow looms. Large fabrics can also be cut into narrow bands. 5/7/9µm (D,E,G). Vetrotex yarns sized with 5312M, T32M, T30C/M, T8C and even TD37C are recommended for this process.

  • UNIDIRECTIONAL REINFORCEMENT

Electrical cables can be reinforced by feeding glass filament yarns during the pultrusion process. This provides the required dimensional stability for the end product. Vetrotex 9µm (G) 68 and 136 yarns sized with T8C are generally used. TD37C yarns impart dimensional stability to optical cable. Sheets of glass filament yarn can also be laminated with a plastic film to produce outstanding adhesive tapes.

  • GLASS CORDS FOR REINFORCEMENT OF AUTOMOTIVE TIMING BELTS

Single glass filament yarns are impregnated with a resorcinol formaldehyde latex to promote adhesion to rubber. Then the impregnated yarns are transformed by plying in a cord that will be used to reinforce timing belts. This imparts the required mechanical properties and dimensional stability. EC9 110 Z20 T63M H9 (G45 1/0 0.5Z) yarn suits the requirements of this application.

  •  LAMINATION

Sheet or textile structures made of glass filament products can be laminated with various substrates. Major applications are paper reinforcement, flooring, adhesive tapes, vapor barrier facing (glass filament structure laminated with aluminum foil) and pressure-sensitive insulation tapes. Vetrotex glass filament yarns provide laminated products with outstanding mechanical and thermal characteristics. The high tensile strength of T63C/M and 876s sized yarns suit the requirements of lamination applications.
