PALGARD TG Material Scratch Resistant Polycarbonate Sheet Notes The table depicting the typical properties of PALGARD TG sheets appears below. Note that some of the displayed properties are typical to polycarbonate the material PALGARD TG is made of while others relate to a typical 3 mm 18 in. thick PALGARD TG 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.
