Polyethylene Density

Measurement of Polyethylene Density

Various grades of polyethylene are defined by their density (e.g. LLDPE, LDPE, HDPE) which relates to the crystallinity of the polymer. As density and crystallinity increase, stiffness increases and impact resistance decreases. Measurement of density is therefore a critical parameter in polyethylene production and Quality Control for its end use.

Our benchtop NMR analyser, MQC+, provides a fast, simple and accurate method of measuring polyethylene density.
