Disclosed is a fire-protection and safety glazing laminate having a haze value less than 4 percent comprising (A) a plurality of high modulus layers laminated with (B) at least one fluoropolymer resin layer wherein (B) resides between (A). The high modulus layers comprise glass, polycarbonate or polyurethane. The fluoropolymer resin layer has a matte finish surface, an embossed finish surface or a combination thereof and is exposed to a corona treatment in an organic gas atmosphere. The high modulus layers are adhered to the fluoropolymer resin layer through a pressure and heat lamination.

Protective glazing laminate

High clarity optical and safety glass laminate interlayer films and optical laminates are described. The films and their laminates comprise very low density polyethylene and/or its copolymers, preferably polymerized with metallocene catalysts, and modified with additives, such as coupling agents, clarifying or nucleation agents, UV-light absorbers, pigment or color concentrate, and IR-light blockers. The very low density polyethylene is laminated to EVA film for improved bondability in optical laminates.

Thermoplastic interlayer film

Optical and firescreening protective glazing laminates comprising fluoropolymer interlayer films are described. The films and their laminates comprise THV and blends of THV with FEP, ECTFE or ECCTFE, and modified with additives, such as coupling agents, pigment or color concentrates, and IR- or UV- light blockers, and may be subjected to a surface corona treatment. The films also may incorporate a fiber mesh for additional reinforcement.
