absorb impacts Polyvinyl Butyral Sheet for glass curtain wall

Polyvinyl Butyral Sheet (PVB film) 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 0.30mm and 1.52 mm. It is the best material for the interlayer of safety glass.

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.
