Xylene solubles in polypropylene is one of standard and important quality control measurements in polymer production processes. Polypropylene is one of the most common polymers in manufacture today. It has an extremely broad range of applications and is produced in a variety of formulations and grades whose properties are optimised for the intended end-use.
Polypropylene is a semi-crystalline polymer where the ratio of the crystalline to amorphous content is one of the major determinants of the properties of the polymer. Xylene solubles are widely used to monitor product reproducibility during synthesis and processing.
Our benchtop NMR analyser, MQC+, provides a fast, simple and accurate method of measuring xylene solubles in polypropylene.
