Melt Flow Rheology Testing for Polyolefins

From Associated Polymer Labs, Inc.
 

 

Melt Rheology Testing provides a quick, efficient, accurate, and cost effective means for detecting potential problems in the processing of polyolefin resins, co-polymers, blends, and rheology modifiers. Plastic melt rheology eliminates the need for time consuming melt tension measurements and inadequate melt index measurements. Detect processing problems of polyolefins before large quantities of off spec product are produced. Before you take your product to the assembly line, make sure you have the rheology data to avoid costly recalls and scrap.

Flow activation energy - calculates Ea by using an Arrhenius fit of zero shear viscosity ? 0 verses temperature. Nornally used with the Ellis Flow Model and TTS modeling of master curves of polyolefins.

Zero shear viscosity - ?0 can be used for several models, calculations, and with dynamic, stress relaxation, creep compliance, and relaxation spectrum data.
