## What is plastic density?

Density of Plastics. Page 1. Density of Plastics. Density is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm3. Specific Gravity (SG) is defined as the ratio of density of the material to the density of water (1 g/cm3) at a specified temperature.

1 200 kg/m³
