high stability fire resistant mica tape

high stability fire resistant mica tape   Product characteristics:   1, With good quality of fireproof performance and fire resistance; 2, Effectively improve the wire and cable insulation quality; 3, Prevent and control electrical accidents, avoid cable fire hazard caused by the overload and short circuit . 4.During combustion of plastic sheath in the electric cable, it can effectively reduce and prevent producing and releasing the toxic smoke and poisonous gas ; 5.Having good characteristic of fire resistance, acid resistance, corona resistance and radiation resistance ; 6.when a fire happens, it can reduce and prevent the spread of flame, and inhibit smoke generation and release. 7. With the excellent quality, good flexibility and tensile strength, the product is suitable to relax on the conductor at the process of high speed winding , and convenient for cable production and processing.
