Quality Control of Polypropylene (PP) Using Near-Infrared Analyzer [Technical Document]
Non-destructive and easy measurement of melt index (melt flow rate) using near-infrared analysis without conducting rheology tests!
【Near Infrared Analyzer Technical Data 9 Petrochemicals Fibers】 To mold polypropylene (PP) resin into the desired shape, it must first be melted, making flow properties a crucial characteristic that influences the manufacturing process. One of the parameters that represent flow properties is the Melt Index (MI), also known as Melt Flow Rate (MFR). This measures the mass of material extruded from a die within a specified time (ASTM D1238). The standard procedure requires many tasks, such as packaging the sample, preheating, and cleaning. Visible near-infrared spectroscopy, which does not require sample pretreatment or chemicals, enables MFR analysis in less than one minute.
