Density of polyolefins measured by nearinfrared spectroscopy
AN-NIR-102Density of polyolefins measured by nearinfrared spectroscopySimple routine analysis of polymer pelletsSummaryAside from melt flow rate, density is the most important parameter to describe theproperties of polyethylene (PE) materials. PE stiffness, rigidity, and heat resistance increasewith higher density. Various testing...
