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. A Specific Grafity of less than 1 means that the material will float in water.
