The TAPPI T 702 standard specifies a Measuring method for the rheological properties of low-density polyethylene (PE) (LDPE) used in extrusion coatings. Rheological properties are an important indicator for evaluating the flow and deformation behavior of materials during processing, which directly affects the mass and performance of extrusion coatings. The standard describes in detail the test equipment, sample preparation, test conditions and operating procedures, including the determination of melt flow rate (MFR) and rheological Linear dispersion. This method can accurately characterize the rheological performance of LDPE, providing a scientific basis for optimizing the extrusion coating process and material selection. The standard applies to polyolefin materials, particularly LDPE for paper and Cardboard extrusion coatings.
