PALGARD Notes The table depicting the typical properties of PALGARD sheets appears below. Note that some of the displayed properties are typical to polycarbonate the material PALGARD is made of while others relate to a typical 3 mm 18 in. thick PALGARD sheet. Material Scratch Resistant Polycarbonate Sheet Conditions units and values in U.S. Customary units are presented in the table within parentheses. All the results depicted in this table were obtained by following the indicated ASTM method except where another method is indicated by the appearance of this symbol b.
