Plastic Properties Technical Information
Dynalab Corp offers technical plastic properties and chemical resistance information for a variety of materials.
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.
