SG of plastic is less compared to other materials influence its price; thus all plastic materials are sold on cost per weight basis. Ultimate tensile strength is the maximum stress the thermoplastic material can withstand before failing, whichever occurs at the higher stress level. Portions throughout the same sample may also differ in density due to differences in crystallinity, thermal history, porosity, or changes to the material composition, such as the addition of a filler or pigment. Structural Shapes 1, Zhongshan Rd., Dacun Township, Changhua County 515, Taiwan (R.O.C. Plastic Material: Density & Specific Gravity - Ji-Horng "Density" has its own unit of measurement, 1 g/cm3 or 1 kg/m3, in contrast, specific gravity has no unit of measurement goes with it; nevertheless, although they don't have the same meaning, they have the same value because density of water is quite close to 1g/cm3. 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. Thermoplastics - Physical Properties - Engineering ToolBox Because its made with long unbranched polymer chains its much stronger and thicker than PET. Density in plastics is the measurement of mass per unit volume. You can target the Engineering ToolBox by using AdWords Managed Placements. 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.

Section Properties Apps Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! The specific gravity of plastic is the ratio of the density of plastic to that of a reference substance (Usually water). Note: Both densities need to be in the same unit as they will cancel each other and produce SG. Polybutylene 0.60 Specific gravity and density are especially relevant because plastic is sold on a cost per pound basis and a lower density or specific gravity means more material per pound or varied part weight.
