Plastic Properties of Polycarbonate (PC)


Polycarbonate (PC) is a linear polycarbonic acid ester prepared from a dihydric phenol. Polycarbonate possesses extraordinarily good dimensional stability with a high impact strength which is maintained over a wide temperature range. This makes PC ideal for the manufacture of laboratory safety shields, vacuum desiccators and centrifuge tubes.

Polycarbonate may be autoclaved (maximum continuous working temperature 130° Celsius, and 140° Celsius for short periods), but some loss in mechanical strength occurs on repeated autoclaving and the equipment should not then be used for vacuum applications. The carbonate linkages in the chain make the material subject to reaction with a variety of concentrated acids and bases and it is soluble in various organic solvents. Dynalab Corp's plastic fabrication shop fabricates thousands of catalog and custom PC products.

Additional Information

  • Polycarbonate is one of the toughest transparent sheets available, about 300 times stronger than single-strength glass.
  • Perfect for guards and glazing. Polycarb machines well and brake forms cold.
  • Can be joined mechanically, solvent bonded, and welded with lots of practice.
  • Typical uses include windows, machine guards, and demonstration shields.
