Rapid plasticity is one of the basic tests used in the natural rubber industry, and is the measurement of compression of a specimen of known thickness at a known temperature under a predetermined load for a known time.  A key measurement in determining the quality of natural rubber is known as the Plasticity Retention Index (PRI)  This measures the resistance of natural rubber to thermal oxidation.

Wallace provide a fully integrated and highly productive solution for determining PRI:

Volumetric Specimen Cutter

The Wallace Specimen Cutter with its compact robust design allows the user to easily cut multiple volumetric samples for use with the P14 Plastimeter and O14 Ageing Oven.  The easy to operate circular motion of the handle, allows the cutting of consistent volumetric samples quickly and easily.
