SUNGEN PVB (POLYVINYL butyral) GLASS INTERLAYERS

The PVB interlayer is a tough, flexible film placed between two or more layers of glass to form laminated glass. It acts as a bonding layer that enhances safety, performance, and durability.

When glass breaks, the PVB interlayer holds the fragments together, preventing them from scattering and significantly reducing the risk of injury.

  • Safety & Impact Resistance
    Holds broken glass in place upon impact
  • Sound Insulation
    Reduces noise transmission through glass
  • UV Protection
    Blocks up to 99% of harmful UV rays
  • Security Enhancement
    Can be layered for higher resistance (anti-bandit / bullet-resistant systems)
  • Flexibility & Adhesion
    Strong bonding with glass while remaining elastic

Application

  • Laminated safety glass (windows, doors, façades)
  • Skylights and overhead glazing
  • Automotive windshields
  • Security and bullet-resistant glass systems
  • Acoustic glass solutions
