How does storage modulus affect extrusion?

For extrusion, the storage modulus can also indicate proper molding conditions. A larger storage modulus in an extruded plastic can result in higher melt strength in the plastic. The higher melt strength in the plastic results in a better extruded profile and film.

Rate-dependent viscoelasticity of an impact-hardening polymer

Calculating the relative increment of storage modulus within the experimental range is the most widely used quantitative method to characterize the frequency-dependent effect, which can be achieved experimentally (usually 0.1 Hz∼100 Hz under oscillatory shear) [13, 22]. We extract the storage modulus at 0.1 rad/s and 100 rad/s from figure 3(a

Introduction to Dynamic Mechanical Analysis and its

If storage modulus is greater than the loss modulus, then the material can be regarded as mainly elastic. Conversely, if loss modulus is greater than storage modulus, then the material is predominantly viscous (it will dissipate more energy than it can store, like a flowing liquid). Since any polymeric material will exhibit both storage and

Why is loss modulus higher than storage modulus?

When the experiment is run at higher frequencies, the storage modulus is higher. The material appears to be stiffer. In contrast, the loss modulus is lower at those high frequencies; the material behaves much less like a viscous liquid. In particular, the sharp drop in loss modulus is related to the relaxation time of the material.
