High Temperature GPC instrument for Quality Control in Polyolefin Production Plants

Polymer Char (Spain) has developed a simplified and compact high temperature GPC equipment, the GPC-QC, in order to fulfill the need in industry of having robust and precise MMD data for process control in polyolefin manufacturing plant laboratories.

Traditionally, some physical parameters related to an average of the MMD, such as melt flow index (MFI) and also the density, have been used in industry for this purpose despite their limited scope. However, for complex multiple reactor products, having multimodal MMD, the limitation of such approach becomes a critical issue.

GPC-QC delivers complete MMD, Short Chain Branching and Intrinsic Viscosity information for one sample in one hour including dissolution, allowing the polyolefin manufacturers to perform a more accurate production control thanks to a precise and complete characterization of the resins and to save costs as per reducing off-grade material production.

The entire process is fully automated in GPC-QC, including delivery of solvent, dissolution and injection, all with a simplified and reliable hardware and software, especially designed with the needs of a QC environment.
