Abstract
(EN)
A polymer film comprising at least two properties selected from (i) a thickness of not greater than 100 μm; (ii) a tensile modulus according to ASTM D882 of at least 5 GPa; (iii) a first optical transparency according to ASTM D1746-15 at 380 nm of less than 50%; (iii) a Yellowing Index according to ASTM E313-15e1 of not greater than 2.5; (iv) a haze as determined according to ASTM D1003-13 of not greater than 1.5%; (v) a pencil hardness of greater than 1H; (vi) a coefficient of moisture expansion ('CME') as determined according to ASTM D5229/D5229M-14 of not greater than 50 ppm; (vii) an elongation at break as determined according to ASTM D5034-09 (2017) of at least 10%; or (viii) a folding endurance as determined according to ASTM D2176-16 at a radius of 1 mm of at least 10,000 folds.
