GAP Polymers provides you with this table below that contains the main 7 types of plastic density that are calculated by dividing the mass of the material by the volume and is expressed normally in g/cm3.
3 paź 2023 · Density in plastics is the measurement of mass per unit volume. It is calculated by dividing the material’s mass by volume and is generally expressed in g/cm3. The density of plastics usually varies with temperature changes. It may also change due to solvent absorption, plasticizer loss, and crystallinity change.
The following table provides a comprehensive list of density values for different polymers and plastics at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
The document lists density values for several common plastics and plastic materials to help identify unknown plastic samples and indicates the importance of accounting for changes in crystallinity, additives, and other factors that can impact plastic density.
