The polytetrafluoroethylene film can achieve DIN4012 fire safety specification level B1, the melting temperature can reach 200 ℃, and it is not easy to catch fire. The quality is light, the ductility is good, the compressive strength is high, and it is not easy to tear. The long service life is less than 30 years, and it is suitable for satisfactory raw materials of double-layer movable roof structure. Because the polytetrafluoroethylene film is dense by fluorine atoms
