Laminated Glass with PVB Film

Laminated Glass with PVB Film sponsored by northglass sunny glass Laminated glass is processed with special technology under high temperature and high pressure by adding one or more layers of Polyvinyl Butyral (PVB) with tough and strong binding between or among two or more glass layers. For the great binding performance, laminated glass could stop external force attack and the chips will be bind with PVB after breakage to avoid making harm to person. And even the glass could still resist attack from wind and rain in breakage status. PVB Film Description: PVB film is a macromolecule material molded by polyvinyl butyral resin that is plastificated and extruded by plasticity DHA.PVB film, with the excellent light transparent performance, heat resisting and cold-resisting, elasticity, is well-sticking to inorganic glass and becoming the best gluey material in the world of making laminated safety glass at present. PVB film is the semitransparent membrane,with no impurity,flexibility and smooth surface.Though there is certain roughness,it has well intensity of stretch proofing and extension at break. PVB film can be divided into refrigeration film and normal temperature film in the way of storage.To avoid being self-sticking,refrigeration films need to be stored and transported under2-10°C ,dry enviroment ,with 2 years storage life.Normal temperature films use isolation membrane to avoid self-sticking,and can be stored for 2 years under the temperature of 10-25°C .New PVB film should be stored at dry enviroment under 20°C without extrusion.
