What is the impact strenght of polycarbonate?

Polycarbonate is almost unbreakable. It is many times more impact resistant than any other transparent material used for glazing purposes. Many types of tests are used to measure impact strength, so it is difficult to compare data. Solid polycarbonate sheets comply with most tests issued on impact strength of glazing materials. To give an idea: a 3 mm-solid polycarbonate sheet withstands the force of a steel ball of about 4 kg dropped from a height of 9.5 m, 3 times in a row. It does not break, or shatter! When you take a look at some of the more industrial applications, you will see that polycarbonate is used for machine glazing, police riot shields, ice-hockey rinks, etc. All applications that require extreme impact resistance.
