The material pellets are loaded into the barrel of a capillary rheometer which is at the test temperature. After it has melted, the material is extruded at a constant volumetric flow rate. Three separate extrudate specimens are taken over a measured time period. The mass of each sample is determined. Knowing the volumetric flow rate, and the time period of each sample taken, we can determine the volume.

Melt Density. This data appears in Matereality as Melt Density.
Number of times this test is repeated: 3
0.3 kg of pellets [details]
Data are used primarily in simulation to calculate thermal diffusivity and estimate flow rates and volume.
