Polymers | ASTM D7399-compliant quantification of polypropylene in polyethylene using Lyza series spectrometer
For polypropylene (PP) and polyethylene (PE) blends, accurate composition is critical, as it affects processing conditions and final product properties. ASTM D7399 describes an FTIR-based method for quantifying PP in PE, which can be easily and reliably performed using Lyza series spectrometer.
Quantifying PP in PE is essential for quality control and material characterization in polyolefin production and recycling.
ASTM D7399, “Determination of the Amount of Polypropylene in Polypropylene/Low Density Polyethylene Mixtures Using Infrared Spectrophotometry,” defines an FTIR-based method that utilizes characteristic absorption bands for this purpose.
The Lyza series FTIR spectrometers provide a robust and user-friendly platform for implementing the standardized method.
