Notes:
Traditionally, an instrument such as an Instron rheometer or thermal analysis is used to characterize the processing conditions of a plastisol. The Instron rheometer is useful only when the material begins to build up mechanical strength. A rheometer such as a Plasti-corder suffers from the requirement of large sample and low sensitivity toward rheology change caused by phase variation. Thermal analysis only responds to the heat capacity and enthalpy changes at transitions occurring during plasticization. The plasticization involves only weak thermal change and is difficult to detect by thermal analysis. However, the more sensitive method of dielectrometric analysis, which needs only a small sample, was used to detect any rheological change of a plastisol during plasticization. Because the information obtained is from molecular motion, the results are accurate and the speed of characterization is rapid.
