polyvinyl butyral sheet (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 polyvinyl butyral sheet 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.
polyvinyl butyral sheet 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.
