Standard Test Methods for Apparent Density, Bulk Factor, and Pourability of Plastic Materials

Importancia y uso:

4.1 These test methods provide useful indexes of performance of plastic materials such as powders and granules with respect to their handling in packaging and fabrication.

4.2 Apparent density is a measure of the fluffiness of a material.

4.3 Bulk factor is a measure of volume change potentially to be expected in fabrication. It is a dimensionless ratio which permits ranking of plastic materials, with respect to volume changes upon fabrication, regardless of their molded or formed density (or specific gravity).

4.4 Pourability characterizes the handling properties of a finely divided plastic material. It is a measure of the readiness with which such materials will flow through hoppers and feed tubes and deliver uniform weights of material.
