Some of our calculators and applications let you save application data to your local computer. First, we have to know that the formula of density is: As formula shown, density is total mass of the object divided by total volume of object, which means: 1 gram per cubic centimetre or 1 kilogram per cubic metre.Density of water is1 gram per cubic centimeter (1 g/cm3), but actually, the exact density of water is not really 1 g/cm3, but rather a bit less (very, very little less) than 1, so we can say thatgenerally the weight and volume of water is the same.What's the meaning of "Specific Gravity"?Specific Gravity means specific value of an object undernormal temperature and pressure. %PDF-1.4 % SPECIFIC GRAVITY- The ratio of the weight of In order to help you make better-informed decisions about the products that you buy, today we will go through the seven different types of plastic, how they differ, and their impact on the environment. 0000050964 00000 n Due to the different density of plastic, we can easily identify different plastics by "Buoyancy Test", for more information, please check out in related articles.

Polystyrene 1.05 Density refers to the mass per unit volume of a material, whereas SG refers to a measure of the ratio of mass of a given volume of material at 23C to the same volume of deionized water. The weight will appear in both metric and common US units. 0000143715 00000 n If you are interested in knowing more about what we do, click here. Density of Plastics: Technical Properties. Density measures the mass per unit volume. It is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm 3. The density of a plastic sample may change due to change in crystallinity, loss of plasticizers, absorption of solvent, etc. 0000009713 00000 n The specimen is weighed first in air (Weight A), and then weighed when immersed in distilled water at 23C (Weight B).
