Construction of PVB film

Product introduction

PVB laminated glass

PVB glass film is composed of polyvinyl butyral resin, the plasticizer DHA plasticizing and extruding a polymer material and molding. PVB glass film with thickness of 0.38mm and 0.76mm has good adhesion to inorganic glass, transparent, heat, cold, moisture resistance, high mechanical strength properties. PVB film is mainly used for laminated glass, PVB film is clamped into a layer of the modified polyvinyl alcohol as the main component in between two pieces of glass. PVB laminated glass is safe, because the function of thermal insulation, noise control and isolation ultraviolet etc, widely used in construction, automotive and other industries.

PVB laminated glass has the following five characteristics

1, security: in the subject to external impact, because the elastic intermediate layer to absorb the shock of the role, can prevent the impact penetration, even if the glass breakage, also produces fine cracks similar to a spider's web, the pieces firmly in the middle layer, will not fall off and hurt, and may continue to be used until replaced.

2, security: PVB laminated glass is very strong, even if the glass crack, with the middle layer of glass firmly stick together, still keeping integrity, the thief can not enter the room.

3, insulation resistance: due to the PVB film with damping function on acoustic propagation, PVB laminated glass can effectively suppress noise, especially at the airport, station, downtown and road on both sides of the buildings in the installation of laminated glass, the sound insulation effect is very obvious.

4, PVB laminated glass anti UV properties: PVB films can absorb more than 99% of the ultra violet radiation, thereby protecting the indoor furniture, plastic products, textile, carpet, art, ancient relics or goods from ultraviolet radiation and the occurrence of fading and aging.

5, energy-saving: laminated architectural glass made of PVB thin films can effectively reduce the sunlight through. The same thickness, laminated glass block heat dark low transmittance of PVB film made of stronger. At present, our company is the domestic production of laminated glass film manufacturer.

Most European and American architectural glass using PVB laminated glass.
