Originally called Melt Flow Index or Melt Index (typically for polyethylene, but applied to a variety of materials), the standard designation today is Melt Mass-Flow Rate or MFR, which is a mass flow expressed (SI …
WebThe spiral flow test is not a viscometric (viscosity measurement) test. It is a test that evaluates the heat-induced melting (or fusion) of encapsulant material under pressure, melt viscosity, and gelation rate. The spiral flow test is used both to compare different materials and to control molding compound quality. WebApr 3, 2024 · Flow curves of polymer melts (the graph of viscosity versus shear rate in the log-log scale) have two distinct behaviors governed by Newtonian and Power law. The Newtonian behavior dominates at very …
