Polyvinyl Butyral (PVB) Interlayer for laminated glass
PVB middle film is translucent membrane, by polyvinyl butyral resin
after plasticizer plasticizing extrusion forming of a kind of
polymer material.Appearance as semi-transparent film, without
impurities, the surface smooth, has a certain roughness and good
softness, with inorganic glass has good adhesive power,
transparent, heat-resistant, cold resistant, resistant to wet and
mechanical strength higher characteristic, is the world
manufacturing laminated, safety glass to use the best adhesive
materials, at the same time in building curtain wall, recruit,
window, bank counter, prison tent out of Windows, and various kinds
of bulletproof glass furnaces screen, and other areas of the
building also has a wide application
Safety
Due to high tenacity and adhesion of PVB films, the films can
endure external impact and are hard to penetrate through. Although
the glass might be broken, it reduces the damage level dramatically
since the glass fragment will not scattered around.
Energy saving
PVB films can reduce radiations from the sun to penetrate into
buildings and automobiles, which can balance the high temperature
sunlight. Thus, will save electricity consumption for air-condition
in buildings and automobiles effectively.
Sound proof
PVB films have a good characteristic of Sound proof, which not only
block external noise from outside but also provide a private space.
Architectural Grade PVB film has wide range usage in the field of
architectural glass,such as construction wall,cover grid,show
wind,bank counter,screen of steel-smeding furnace and bulletproof
glass and so on.
