Fire-resistant Phlogopite tapes are compounded of Phlogopite micas and glass fiber clothes with silicone resin as their adhesive; they are mainly used as fire-resistant insulating materials between cables' core lines and sheaths. Phlogopite mica tapes can resist extreme temperature up to 800 Celsius degree. Fire resistance experiments show that breakdown will surely not occur within three hours under the conditions of 800 Celsius degree and 1500V for cables enveloped by mica tapes. Phlogopite mica tapes have good flexibility and high tensile strength and the length of a single roll can be up to 2,000 meters.

Fire-resistant Phlogopite tapes have excellent fire resistance, acid and alkali resistance, anti-corona, anti-radiation, non-flammability and high heat resistance. Cables that use fire-resistant mica tapes in their heat-resistant plastic sheaths will reduce and prevent the generation and escape of poisonous smoke and gas. They are widely used in high-rise buildings, underground railways, underground streets, large-scale power plants, cable factories, and other important enterprises.
