WebSpecific Gravity (SG) is defined as the ratio of density of the material to the density of water (1 g/cm3) at a specified temperature. Example: A gallon of oil weighs 9.5 lbs per gallon9.5 lbs / 8 = 1.187 specific gravity. 0000169321 00000 n 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. ), Copyright 2000 - 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. Urine normally has a specific gravity between 1.003 and 1.035. Polypropylene 0.90-0.92 Despite its many advantages and efforts made by the plastic industry to increase its reusability, PVC is still hardly recyclable and should therefore be avoided, whenever possible. Polyacronitrile 1.17 In its rigid form, PVC is largely used in the building and construction industry to produce door and window profiles and pipes (drinking and wastewater).
