GLASS FIBER TEXTILE
GLASS FIBER TEXTILE PRODUCTS
A complete range of Glass Fiber Textile Products for thermal insulation and seals for high temperatures: Ropes, Braids, Sleeves, Tapes, Fabrics and Insulating Products
The base material of Tespe Glass Fiber Textile Products consists of 6 - 9 microns “E” Glass Fiber Filament Yarns that can be voluminized, texturized, plyed, reinforced with steel wire, etc.
They are inorganic, steril, incombustible, totally Asbestos-Free and contain neither toxic matter nor heavy metals. Moreover, they do not cause skin irritations.
