PVB layer middle films endure external impact hard to penetrate
through
PVB Film is a macro molecule material made with Polyvinyl Butyral
resin plasticized and extruded by plasticize and additives,and
mainly used for producing laminated safety glass.
The advantages and characteristics of PVB layer films
High Safety building material:
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.
High Energy saving building material:
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.
Absorption of UV rays:
PVB films have a good characteristic of UV rays absorption, prevent
discoloration due to UV rays from the sun.
Aesthetics of buildings:
PVB films provide multiple colors to choose, harmonizing with the
surroundings and satisfying designers demand.

Every layer of PVB film rolls should be sepatared by PE film and
vacuumed by aluminum foil,and put into wooden case.
The product should be stocked in a clean warehouse and normal
temperature.It is prohibited to leave it under direct sunlight.Once
the packing is broken or opened,it should be stocked under
temperature of 15-25 ℃ and a relative humidity of 20%-40%.
Well-packed and under nomal temperature,the product has a quality
guarantee of 2 years.
