Polycarbonate is an extremely tough crystal-clear plastic. It has very high impact strength and tensile strength. It has relatively poor chemical resistance.
Polycarbonate used to be used for food containers but recent concerns about BPA have reduced its use significantly.

A lot of polycarbonate gets used in alloys with other materials such as ABS and ASA.
