Black fiberglass tissue, often referred to as black glass fiber cloth, is known for its high-temperature resistance, corrosion resistance, and electrical insulation properties. It is primarily composed of glass fibers that have been treated with a black resin to give it color and additional properties. The chemical properties include resistance to alkalis, acids, and many organic solvents. It does not conduct electricity and has low thermal conductivity, making it suitable for thermal insulation. The black fiberglass tissue is also non-flammable and has good mechanical strength, which makes it useful in various industrial applications where these properties are beneficial.
