Introduction

Polycarbonate, also known as PC, has been mass-produced since 1958.
  - It is a thermoplastic polycondensate.
- Applications: PC can be used to make optical lenses, windows, medical items, CD's, and power tool housings. It can also be used in truck cabs.
- General properties: It has excellent strength, toughness, dimensional stability, dielectric strength, flame retardancy, and impact resistance (highest among transparent rigid materials). It is, however, susceptible to stress cracking with aromatic solvents, and is difficult to machine.
- Trade Name: Lexan, Makrolon.
