Eastman Saflex® RB11 Clear PVB interlayer
Categories: Polymer; Film

Material Notes: Saflex® Clear PVB interlayer, our most popular formulation, is available in two different adhesion levels for architectural applications. These different adhesion levels are generally selected based on the laminator’s processing parameters. Both formulations give architects and builders the ability to meet or exceed the human safety impact requirements for laminated safety glass with properly produced laminates.
  • Protects building occupants and pedestrians from flying and falling glass shards after accidental breakage
  • Provides security through burglary and forced-entry resistance and ballistics and bomb blast protection
  • Provides severe windstorm and debris-impact resistance
  • Reduces the transmission of unwanted sound into a building’s environment or between walls
Applications:
Interior: Partitions, doors, windows, skylights, furniture, balustrades, retail shelving, flooring
Exterior: Doors, windows, curtain walls, wall coverings, and overhead glazing
