Textured glass fibre fabrics (GT fabrics) are made from 2 types of glass: E-glass 600°C and HR-glass 800°C. Each glass type is providing its own specific qualities.
(E-Glass 600º C)
Textured glass fibre fabrics (GT) with thermal resistance of 600°C 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.
Application: GT fabrics are used as heat and acoustic insulating material, as a heat absorber for compensators, and for the production of protective clothes.
- mass per unit area: 280 up to 1200 g/m²;
- GT fabrics are manufactured with cut and/or tuck-in selvedge.
Designation: e.g. GT-550 TS, where:
GT – type (E-glass textured fabric),
550 - mass per unit area,g/m²,
TS - edge type (tucked-in).
(HR-Glass 800º C)
HR-glass is alkali-free aluminosilicate glass that does not contain boron oxide and fluorine. This glass type could fully substitute E-glass in various aspects. The most important feature of this type of glass is its thermal resistance of up to 800°C.
Advantages of HR glass fibre compared to E-glass:
- better chemical resistance, particularly in acidic, as well as alkaline and water environments;
- better thermal resistance;
- better dielectric properties;
- equal durability;
- environmentally friendly glass melting process - does not create dust emissions containing boron oxide.
