describe

overview

Extrusion capillary rheometer is a device used to measure shear stress rate under high stress. It can measure the flowability and curing speed of thermosetting materials, draw stress-strain curves and plasticization curves of thermoplastic materials, and determine the temperature of softening point, melting point, and flow point. Measuring the viscosity and viscous flow activation of polymer melts, as well as studying the process conditions of melt spinning.

Used to measure the relationship between shear stress and shear rate of polymer melts in capillaries, directly observe the appearance of extruded materials, study the elasticity and instability of melts by changing the aspect ratio, and determine changes in the state of polymers. The study of polymer rheological properties can not only provide optimal processing conditions and data for plastic machinery design parameters, but also obtain useful data on structure and molecular parameters in material selection and raw material modification. There are more simulation processing modes and a wider range of shear rates.
