Glass cloths are the most flexible and conformable backings used for adhesive tapes. Due to the glass fibers in the cloth (an inorganic material), it is non-flammable and high temperature resistant. Glass cloths can be used at a constant temperature of 180°C (356°F), and offers good solvent and chemical resistance. The tensile strength of glass cloth is excellent (almost 6 times that of 0.025 mm PET). Glass cloth tapes can be used for a wide range of applications: insulation, inner and outer layer wrapping of electrical coils, and bobbins.
