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:
