What Is Melt Viscosity at Ellen Franklin blog

What Is Melt Viscosity. Melt viscosity refers to the measure of a polymer's resistance to flow when it is in a molten state. A thermoplastic resin is in the solid state at temperatures less than the melting point, and when it is heated above the melting point, it melts and thus exhibits. The usual symbol is η but μ is sometimes used. The melt viscosity of a polymer at a given temperature is a measure of the rate at which chains can move relative to each other. The viscosity in this region is known as the zero shear, or newtonian, viscosity ho. Melt viscosity changes continuously along the length of the screw, in response to shear rate and temperature of the polymer. Melt viscosity is a constant at low shear rates or frequencies. Dynamic viscosity is an alternative name for the viscosity or coeficient of viscosity of a fluid. The greater the shear rate, the lower the viscosity of the melt, meaning it flows more easily as it moves faster. This property is crucial for processing. In the cgs system, the units are dyne sec. For low molecular weight polymers in.
