 Density of Plastic material 

 

Plastic density presents the total mass of the material divided by the total volume of the material.

density is 1 kilogram per cubic meter or 1 gram per cubic meter.

D=M/V ___ Density=Mass/Volume

To determine the density of plastic materials, you have two options. The first one is to test the solid plastics in water, the second is to test the solid plastic in a liquid other than water. The first choice is the more common test that can be performed with plastic sheets.

Generally water density near to 1 , so if plastic material flot on water , means density is less than or equal to to 1 , if sink in the water means high density.

Bulk Density 

The bulk density of plastic materials is the weight of material depending on the specific volume. You can express bulk density in (g/cc) gram per cubic centimeter, (b/cu ft) pounds per cubic foot and (KG/L) Kilogram per liter.

For instance, if you want to determine the bulk density of PET Material, the virgin PET density differs from PET sheets.

When it comes to drying operations, bulk density plays the biggest role. You must first determine the materials’ weight to choose the right temperature range for the material residence period.
