Applications and Design It holds the number one spot because of its widespread utility. 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. There are two basic test procedures- Method A and Method B. The more common being Method A, can be used with sheet, rod, tube and molded articles.

The tests for density and SG are particularly significant in the custom sheet industry because plastic sheet is sold on a cost per pound basis. 0000156682 00000 n Vibration Engineering Polycarbonate 1.2 But they can also be found on mobile phones and, more frequently, in compact-discs (CD). Specific gravity of a material can be calculated by following equation: The testing method of SG for plastic systems is ASTM D792 and ISO 1183. SG of plastic is less compared to other materials influence its price; thus all plastic materials are sold on cost per weight basis. 0000161897 00000 n 0000124314 00000 n Though some manufacturers use grams per cubic centimeter to indicate the weight of their products, others merely provide the specific gravity of their material. 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. Plastic (CR-39) and Crown Glass are considered base index with indices of 1.498 and 1.52 respectively. Due to the different density of plastic, we can easily identify different plastics by "Buoyancy Test", for more information, please check out in related articles. WebSpecific Gravity (SG) is defined as the ratio of density of the material to the density of water (1 g/cm3) at a specified temperature. 0000102892 00000 n 0000051762 00000 n The information contained in this article is for general information purposes only. 0000072608 00000 n Please read Google Privacy & Terms for more information about how you can control adserving and the information collected. 0000167357 00000 n Also, it is relatively hard and resistant to impact and can be subjected to temperatures of up to 120 C without being affected.

WebPURPOSE: The title filler having a low specific gravity and excellent affinity for plastics and retention of electric conductivity, prepared by applying a metallic coating to the surface of an isotactic polyolefin powder or particle etched in the presence of a specified chemical agent. First, we have to know that the formula of density is: As formula shown, density is total mass of the object divided by total volume of object, which means: 1 gram per cubic centimetre or 1 kilogram per cubic metre.Density of water is1 gram per cubic centimeter (1 g/cm3), but actually, the exact density of water is not really 1 g/cm3, but rather a bit less (very, very little less) than 1, so we can say thatgenerally the weight and volume of water is the same.What's the meaning of "Specific Gravity"?Specific Gravity means specific value of an object undernormal temperature and pressure. Styrene-butadiene 0.93 Yield point is the first point where the specimen yields, where the specimen's cross-sectional area begins to contract significantly, or where the strain can increase without increase in the stress.

The purpose was to provide a consistent national system to facilitate recycling of post-consumer 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). Over 12,000 ASTM standards operate globally, including tests specific to plastics, to help consumers have confidence that the products they purchase will perform as expected. However, various factors can affect density such as crystallinity, loss of plasticizer or absorption of solvent.
