PVB

Application:
PVB is produced by extrusion of PVB resin, plasticizer and additives. Due to its excellent transparency, heat resistance, toughness and flexibility, PVB is widely used for laminated glass production.
Laminated glass is a type of safety glass that has two or more layers of glass. It is made by bonding two or more pieces of glass with PVB as interlayer using heat and pressure.  PVB interlayer gives the glass additional physical properties including high penetration resistance, sound insulation, thermal insulation and UV block. Moreover, PVB has similar transmittance as glass. With same purity and transparency as ordinary glass, laminated glass is commonly used in automobile and architectural application such as windshield and curtain wall.
