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. HGCs are far more dense than existing plasticse.g., 40% glass-filled nylon has a specific gravity (SG) of just 1.46and are weighty enough to compare with aluminum (2.7 SG), zinc (6.64), steel (7.6), and lead-antimony (11.35). 0000137613 00000 n 0000004768 00000 n Our Polycarbonate sheet offers a levelof safety that no other clear glazing material can match.

Web most plastic baby bottles 5-gallon water bottles sport water bottles metal food can liners clear plastic sippy cups some clear plastic cutlery Mixed resin plastics like #7 are difficult, if not impossible, to recycle. Beverage bottles are among the main plastic items that come for PET. From here density and SG are calculated using the following formulas: Specific Gravity = (Weight A / Weight B)Density = (Weight A / Weight B) * 0.9976 g/cm3 , where 0.9976 g/cm3 is equal to the density of distilled water at 23C. Polypropylene 0.90-0.92 Water's weight is one gram per cubic centimeter - a material with, for example, 1.5 specific density would then weigh 1.5 grams per cubic centimeter. It is 250 times stronger and just as clear as glass.
