The structure and characteristics of the explosion-proof membrane 

 1, anti-wear layer: consists of wear-resistant polyurethane hardness up to 4H; 
 2, colored PET safe grass-roots level: high strength, high transparent PET and pigment melt extrusion of biaxially oriented system, the pigment caught in the inside of the PET film to prevent oxidation of color, life for eight years; 
 3, metal insulation: PET film by vacuum evaporation or magnetron sputtering of metal aluminum, silver, nickel, etc. have a higher reflectivity to the infrared nanoscale metal layer; 
 4, laminating adhesives: weather resistance, good high transparent polyurethane adhesive composition; 
 UV absorption layer: consists of special UV absorbers can block 99% of the ultraviolet; 
 6, transparent PET grass-roots level: high strength, high transparent PET membrane, caught in the middle of the metal layer to prevent the metal oxide to extend the life of the metal film; 
 7, the installation adhesive: good weather resistance and high transparent acrylic adhesive; 
 8, the high transparent PET film.
