The specific gravity of plastic is the ratio of the density of plastic to that of a reference substance (Usually water).
Expanded PVC sheet plastic is the ideal material where durable construction materials are needed. SPECIFIC GRAVITY- The ratio of the weight of the molded piece as compared to the weight of an equal volume of water ASTM D792. Specific Gravity (SG) is defined as the ratio of WebSpecific gravity is the ratio of the density of a substance to the density of the same volume of water. When mixed with other substances, It can be made softer and more flexible and applied to plumbing, wiring, and electrical cable insulation and flooring. We carry a large selection of American-made Tamco industrial strength tanks. Polybutylene 0.60 Used in plastic bags,six-pack rings, various containers, dispensing bottles, and most famously for plastic wraps, is not often recycled through curbside programs. 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. Heres a brief recap of what we have learned so far: We hope this blog post has provided some clarity about the differences among all these plastic types. The member-related functions have been closed due to the deactivation of cookies. One of the most commonly used plastics, our heavy duty acrylonitrile butadiene styrene, or ABS sheeting, has a high impact resistance and durability to be used for automotive, printing, and display applications. 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. Finishing and Plating Acrylic sheeting, commonly referred to as plexiglass sheeting, is the most common alternative to traditional glass. Minerals and other Materials - Specific Gravities Specific gravities for minerals and other materials. Polypropylene 0.90-0.92 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.
