Plasticity measurement.

Plasticity of natural or unvulcanized compounded rubber is measured to international standards by the Rapid Plastimeter. With the Model P14/VT, which comes with printer and data input terminal, operators can vary the platen temperature between 60-180[degrees]C. Plasticity measurement using the P14 VFF is said to offer a quick, low cost method of characterizing the flow behavior of rubber compounds. Indeed, for some applications, the model may be a better alternative to traditional viscosity measuring instruments, according to the manufacturer. The variable temperature feature is said to allow the user much greater flexibility when developing new compounds, as well as performing standard plasticity tests on natural rubber with the platens at a constant 100[degrees]C. The P14 model, marketed under the Cogenix brand, features a c-frame design, said to provide safe and easy access for the operator when loading and removing samples from between the heated platens. Clear instructions are digitally displayed so that the operator can have the instrument ready for sample testing in seconds. The Rapid Plastimeter may be used in conjunction with the company's aging chamber. (Wallace Instruments)
