6 FAQs about [How big is the storage modulus of acrylic]

What is a modulus of acrylic?

Modulus of acrylic, E = 2.76×10 9 N/m 2 using equation E4. Figure 6 shows the how the stress for each channels compare in a graphical representation. It can be are greater. This is because greater mass causes greater stress and the difference of stress in each gauge positions gets more significant.

What is the storage modulus of a miniemulsion polymer?

The storage modulus as a function of temperature at six different maleic acid concentrations is shown in Fig. 12.11. These are compared to the storage modulus of a miniemulsion polymer that contains no maleic acid. The storage moduli of the AOME-co-MMA-co-MA polymers are slightly higher than that of the AOME-co-MMA polymer.

What is storage modulus?

This action is not available. The storage modulus measures the resistance to deformation in an elastic solid. It's related to the proportionality constant between stress and strain in Hooke's Law, which states that extension increases with force.

What is a storage modulus in a nozzle extruder?

The storage modulus determines the solid-like character of a polymer. When the storage modulus is high, the more difficult it is to break down the polymer, which makes it more difficult to force through a nozzle extruder. Therefore, the nozzle can become clogged and the polymer cannot pass through the opening.

What is the storage modulus of a polymer that contains maleic acid?

The storage modulus of the polymers that contain maleic acid as a function of temperature. The thin line represents a comparable polymer that contains no maleic acid. Figure 12.12. The storage and loss modulus of an AOME-co-MMA-co-MA polymer. Wibke Markgraf, ... Stephan Peth, in Soil and Tillage Research, 2006

What happens if a polymer has a low storage modulus?

The reverse is true for a low storage modulus. In this case, the polymer is too liquid-like and may begin to drip out of the nozzle, and may not hold its shape very well . A similar parameter is loss modulus, which is the opposite of storage modulus, the polymer’s liquid-like character.
