Polycarbonate (PC) is an amorphous thermoplastic polymer. Amorphous polymers do not have defined melting points but ranges at which they soften (called the glass transition temperature).
Polycarbonate has excellent toughness, strength, transparency and dimensional and color stability. It has higher impact resistance than nylon 6 and nylon 6,6. Its drawbacks are lower resistance to chemicals and organic solvents.
