Web10 apr. 2024 · For example, look at the viscosity of the material when the melt temperature is 204C and the shear rate is 2500 sec–1. You should come up with 55 Pa-sec. Now look at the same shear rate point for the curve generated at 249C. The viscosity has dropped to 40 Pa-sec. Now comes the good part. WebIn general, the melt viscosity properties tend to depend on the molecular weight of the PPS polymer. For reinforced grades and elastomer improvement grades, however, the fluidity is not necessarily correlated to the molecular weight because of the influence of the reinforcement content and other factors. Ⅰ. Melt Mass-Flow Rate (MFR)
WebEl índice de fluidez es una prueba reológica básica que se realiza a un polímero para conocer su fluidez. Se mide en g /10 min. Se define como la cantidad de material (medido en gramos) que fluye a través del orificio de un dado capilar en 10 minutos, manteniendo constantes presión y temperatura estándares. WebMelt Flow Rate measures the rate of extrusion of thermoplastics through an orifice at a prescribed temperature and load. It provides a means of measuring flow of a melted material, which can be used to differentiate grades as with polyethylene, or determine the extent of degradation of the plastic as a result of molding.
