III. Test items
1. Constant speed shear test: measure shear stress and shear rate curves, shear viscosity and shear rate curves
2. Constant pressure shear test: measure the shear viscosity and shear rate curve
3. Step shear rate test: Different shear rates can be set according to user requirements, and shear stress and
shear rate curves, shear viscosity and shear rate curves can be measured. During the experiment, the
fracture of the melt and the minimum flow pressure and shear rate of the melt can be determined based
on the changes in the curves
a) Flow/non flow testing: measuring the relationship between viscosity and temperature, accurately
determining the minimum flow velocity
b) Melt fracture and flow instability: Study of flow instability phenomena, including melt fracture and melt
cracking
