architectural grade clear PVB film middle layer for building glass
PVB is the abbreviation of polyvinyl butyral. PVB film is made from
PVB resin and plasticizer. It is a non-toxic and smell-free soft
sheet material with thickness between 0.38mm and 1.14 mm (0.3mm
specially for some market). It is the best material for the
interlayer of safety glass.
The advantages and characteristics of PVB 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.
