Because of this difference, when comparing polypropylene sheet to PET sheet, holding constant gauge and size, customers can see approximately a 30% density reduction from PET to PP and an increased yield on pounds purchased. Sg = Specific Gravity of the substance Specific gravity (S.G.) is a measure of the relative density of a substance as compared to the density of water at a standard temperature. WebSpecific gravity is the (unit less) ratio of the solid wood density to the density of water at the same temperature. This bucket is economically priced, while still featuring premium bucket quality and durability.
