WebSpecific gravity is a measure of the ratio of mass of a given volume of material at 23C to the same volume of deionized water. There are two basic test procedures to determine the density of a material method A, used for testing solid plastics in water, and method B, used for testing solid plastics in a liquid other than water. Specific Gravity (SG) is defined as the ratio of Density refers to the mass per unit volume of a material, whereas SG refers to a measure of the ratio of mass of a given volume of material at 23C to the same volume of deionized water. Some elements may not work properly. Note: Both densities need to be in the same unit as they will cancel each other and produce SG. 0000129490 00000 n 0000138434 00000 n Polychloroprene rubber 1.23 0000168199 00000 n We don't collect information from our users. 0000124655 00000 n Plastics have a really wide specific gravity range depending on its composition. | Contact, Home The purpose was to provide a consistent national system to facilitate recycling of post-consumer plastics." ), Plastic Material: Density & Specific Gravity.

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). It is common to use the 0000156682 00000 n Therefore, the specific gravity (which is dimensionless) for a liquid has the same numerical value as its density in units of g/cm3. Specially designed for marine applications, antiskid HDPE sheeting offers superior durability with the additional benefit of a non-skid surface perfect for high-traffic marine surfaces. Training Online Engineering. 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. 0000006688 00000 n Physicists use 39.2 F (4 C) as the standard, but engineers ordinarily use 60 F. In the International System of Units (SI Units), the density of water is 1.00 g/cm3 at the standard temperature. Perhaps better known by its commercial name Styrofoam its highly inflammable and dangerous as it can leach harmful chemicals, especially when heated (which often happens because, as its found in disposable take-out containers, people oftentimes microwave it to heat up the food inside it). 2023, by Engineers Edge, LLC www.engineersedge.com 7 0 obj<> endobj xref 7 103 0000000016 00000 n WebDensity of Plastics Density is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm3. 0000173123 00000 n 0000125208 00000 n WebMaterial density g/cc 1 g/cc = material density = specific gravity Therefore, knowing the specific gravity and with the help of the handy conversion table on the shared drive one 0000140352 00000 n Power Transmission Tech. 0000142018 00000 n 1 cm3 water weighs 1 g (as mentioned, density of water is 1g/cm3), and 1cm3 aluminum weighs 2.7 g (the density is 2.7 g/cm3), thus specific gravity of aluminum is 2.7 1 = 2.7 (which has the same value with density), **Tip: To look it up efficiently, mobile phone viewer, please use site searching, computer viewer, please use "Ctrl + F"**, Remarks: Glass Fiber (GF), Carbon Fiber (CF), Mineral Fiber (MF), Impact Modified (IM), Low Friction (LF), Talc Filled (TF), Ultra High Molecular Weight Polyethylene (UHMWPE), Crosslinked Polyethylene (XLPE), Density of Chemical Additives forInjection Molding. 0000164707 00000 n 0000136804 00000 n Method A is the more common test method used, and can be performed with sheet, rod, tube and molded pieces of plastic materials that are not affected by water. 6, Sec. 6I&dsV.G{w+Z#Ot>wY[~JKWr#oyOIIl(RV[U|i:n0qfB#}CNs,%|PEyeTeB You can target the Engineering ToolBox by using AdWords Managed Placements.
