[0068] [table 3]
[0069] Table 3 details the formulation of this example, where "phr" refers to parts per hundred resin. First, the antioxidant and the UV stabilizer were mixed into an additive masterbatch by a twin-screw extruder at 170°C. The mixture of base resin, catalyst masterbatch and additive masterbatch was then extruded through a single screw extruder at 170°C into a 0.5 mm thick film. The extruded films were then tested in a series of characterization steps.
[0070] The film was first laminated between two glass plates, each 3 mm thick, at 85° C. in a standard flat-bed vacuum bag laminator with a total cycle time of 60 minutes. The resulting laminate was free of voids and other visible defects. The post-lamination peel strength between foil and glass was measured to be in excess of 10 N / mm by a standard 90° peel test using a standard tensile tester. Standard creep tests were then performed on the laminated glass panels at 85°C and 85% relative humi...

[0073] [Table 4]
[0074] Table 4 details the recipe for this example. First, the antioxidant, UV absorber and UV stabilizer were mixed into an additive masterbatch by a twin-screw extruder at 170°C. The base resin (in this case comprising a 50:50 blend of two different resins as indicated in the table), catalyst masterbatch and additive masterbatch were then passed through a single screw extruder at 170°C. The mixture was extruded into a 0.5 mm thick film. The extruded films were then tested in a series of characterization steps.
[0075] The film was first laminated between two glass plates, each 3 mm thick, at 85° C. in a standard flat-bed vacuum bag laminator with a total cycle time of 60 minutes. The resulting laminate was free of voids and other visible defects. After lamination, the peel strength between foil and glass was measured to exceed 5 N / mm by the standard 90° peel test as described above. Standard creep testing (as described above) was then per...

[0078] [table 5]
[0079] Table 5 details the recipe for this example. First, the antioxidant, UV absorber and UV stabilizer were mixed into an additive masterbatch by a twin-screw extruder at 170°C. The mixture of base resin, catalyst masterbatch and additive masterbatch was then extruded through a single screw extruder at 170°C into a 0.5 mm thick film. The extruded films were then tested in a series of characterization steps.
[0080] The film was first laminated between two glass plates, each 3 mm thick, at 85° C. in a standard flat-bed vacuum bag laminator with a total cycle time of 60 minutes. The resulting laminate was free of voids and other visible defects. After lamination, the peel strength between foil and glass was measured to exceed 5 N / mm by the standard 90° peel test as described above. The laminated glass panels were then subjected to the same creep test as above at 85°C and 85% relative humidity, showing no creep after 100 hours.
