The other important attributes of polycarbonate are transparency (a quality shared with all other unadulterated amorphous thermoplastics) and nonflammability the critical oxygen index is 25% for unfilled polymer. However, with this index, it is likely that PC would continue to burn in a hot environment. Also on the debit side, the chemical resistance is not outstanding, and satisfactory weathering resistance is only achieved with additives.
