Technical, coated and laminated glass fibre fabrics

Description

Technical fabrics (TG) are made of alkali-free alumina borosilicate E-type glass fibre yarns with heat resistance up to 600°C. For the production TG fabrics we use yarns with a filament diameter of 6, 9, 11 or 13 µm.

Textured glass fibre fabrics (type GT) are made of alkali-free alumina borosilicate E-type glass fibre yarns. Textured yarns with a filament diameter of 6 and 9 µm are used for the production of textured fabrics, type GT.

Glass fibre products with a high SiO2 content are excellent high temperature insulators and can be used over long periods without losing the properties and without melting and vaporising at temperatures of up to 1000ºC.

Technical coated glass fibre fabrics for industrial insulation as well as for fire and smoke protection are made from alkali free alumina borosilicate E-type glass fibre yarns. For the production of coated glass fibre fabrics the yarns used have a filament diameter of 9µm. High silica coated fabrics, a high SiO2 content adds additional features for raw glass fibre fabrics. In the case of thermally untreated woven fabrics, silica materials shrink by up to 12% (+/-1%) at 1000°C while thermally treated woven fabrics and scrims can shrink by 1% till 3%, depending on the treatment process. Glass woven fabrics are characterised by their high tearing strength and the low strain, despite their low weight. Coating: Polyurethane Premium (PU); Polyurethane Industrial (PH), Silicone Premium (SI); Silicone Industrial (SH); Gum stock (GS); Intumescent graphite filled coating (BI); Neoprene (N); Coatings in combination with Aluminum foil or metallised Polyester foil (AL or MPF).

Laminates for thermal insulation can be made from from 2 types of glass (E-glass 600°C and SiO2-glass 1000+°C). In the project stage there is HR-glass (800°C), from which we will offer TG fabrics in the future. Each glass type is providing its own specific qualities. The temperature of 600°C, 1000°C  given here refers to the loomstate fabric. Finishes such as laminating have an effect on the temperature resistance. Application features from laminating: media-tight, gas-tight, resistant to abrasion and buckling, high thermal radiation reflection capability.
