high transmittance PVB film interlayer for glass curtain wall
PVB Film is used as interlayer film in production of laminated
safety glass for Automotive front glass and buildings; And
potential costumers of PVB Films are glass factories. The PVB film
is a high molecular polymer made from PVB resin and plasticizer,
together With different additives according to different
application and formed through Plasticization and extrusion by
extruder. It is semitransparent, elastic, flat, without Impurity
but with some roughness.
The PVB film is a strong adhesive, well-known for its properties as
high transparency, Heat-resisting, cold-resistant, moisture-proof,
and irradiation resistance. Insulation and High mechanical strength
and the best adhesive material for laminated glass.
The laminated safe glass can enhance elasticity of glass and absorb
impact forces from Outside. Even the glass Is broken, the film
still adheres tightly to the surface of glass and Keeps the
structure as usual, which protects people from accidental injure
and robbery.
PVB film can damp sound waves and effectively block the spread of
the noise. It can also Effectively block the penetration of
ultraviolet ray to reduce greatly heat and the damages To human
body and objects.
