Polycarbonate PC 1000

Polycarbonate PC 1000 is a transparent thermoplastic that exhibits extraordinary impact resistance and strength. Commonly known as Lexan or Hyzod, this material exhibits excellent electrical properties.  Its visual clarity, low moisture absorption rate and good chemical resistance make it an extremely versatile as an engineering material and allows it to be used in a multitude of industrial applications.

Polycarbonate PC 1000 is a mechanical grade material available in several sizes of rod and sheet.  When polished, it has a light transmittance of approximately 88% and is stress relieved making it ideal for close tolerance machined parts.  Machined with conventional metal working equipment, tolerances to +/-.001 can be achieved with experience.
