RDAII Torsional Rheometer:

• Melt viscosities, or resistances to deformation, of neat polymers and masterbatches under torsional shear flow.   

• Melt strengths of the crystalline and amorphous phases of the polymer

RSAII Extensional Rheometer:

• Solid film’s extensional viscosities during repetitive elongation and retraction to a certain strain level at a certain temperature

DMA• Dynamic Mechanical Analysis (DMA)

technique used to study and characterize materials.

• A sinusoidal stress is applied and the strain in the material is measured, allowing one to determine the complex modulus.

• The temperature of the sample or the frequency of the stress are often varied, leading to variations in the complex modulus.
