The wallace rapid plastimeter measures the plasticity or viscosity of unvulcanised rubbers. The test is simple, clean and quick. The instrument is used in conjunction with the wallace -mrpra ageing chamber (cat. Ref. O14) to determine the plasticity retention index (pri) of raw natural rubbers.
the variable temperature model (p14/vt) characterises the flow behaviour of synthetic rubber compounds as, unlike the other models, its platen temperatures can be varied between 60°c and 180°c. For some applications the p14/vt offers a quick, low cost alternative to a mooney viscosity test.
the instrument is supplied in four versions and each version comes complete with specimen cutter. The instrument is shipped with 10mm dia top platen installed and alternative top platens of 7. 3 and 14mm diameter are supplied as accessories. The platens are easily interchangeable.
