Specific Gravity Polyacronitrile 1.17 Applications and Design 0000005946 00000 n 1 gallon of water weighs 8.33 lbs. Therefore, for the same 1cm volume, the melted plastic weighs less than the solid plastic (0.933 g/cm vs. 1.054 g/cm). So, keep reading! Specific gravity and density are especially relevant because plastic is sold on a cost per pound basis and a lower density or specific Some manufacturers may consider testing and certification an obstacle to overcome to get to market. Example: A gallon of oil weighs 9.5 lbs per gallon9.5 lbs / 8 = 1.187 specific gravity. Plastics 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).
