Q: What is the impact strength of polycarbonate?

A: Polycarbonate is almost unbreakable. For instance 3 mm solid polycarbonate sheet withstands 4 kg ball dropped from a height of 9.5 m, 3 times in a row, and it does not break or shatter. So, for this reason, polycarbonate is used for cop riot shields, ice-hockey rinks, airplane windows, and all applications that require extreme impact resistance .
