Polycarbonate Characteristics

Polycarbonate has outstanding impact resistance over a wide temperature range as well as fairly good heat resistance.  Lexan® offers an excellent combination of toughness, dimensional stability and heat and flame resistance. Creep resistance is also excellent across a broad temperature range. This thermoplastic material is easily machined and can be cold formed as well. It is available in clear and color. Because of its many advantages, Lexan® is a good choice for many applications.
