Abstract
Abstract The results indicate that the hanging-strip method provides good values of η0 under favorable circumstances. The value of the method lies in the convenience and simplicity of the experiment. With little more than a meter stick and a clock, one can estimate zero-shear viscosities which are above 0.1 MPa·s. Careful testing is very important to avoid the effects of molding history and clamping, and to assure that the time-dependence of specimen elongation conforms to the Newtonian liquid model.
