PVB film

is a kind of polymer material made of polyvinyl butyrate resin plasticized and extruded by plasticizer. The appearance is translucent film with no impurities, flat surface, certain roughness and good softness. It has good adhesion to inorganic glass, and has the characteristics of transparency, heat resistance, cold resistance, moisture resistance and high mechanical strength. It is the best bonding material for the manufacture of laminated and safety glass. This kind of laminated glass not only has excellent optical properties, but also has special properties such as penetration resistance, high and low temperature impact resistance, sound insulation, heat insulation, UV insulation, high and low temperature climate resistance, etc. It is widely used in national defense, transportation, construction, decoration and other industries. It is also widely used in building curtain wall, canopy, window, bank counter, prison window, steel furnace screen and various bullet-proof glass and other construction fields.
