Animals do not recognize it as artificial and may mistake it for food causing serious effects on the health of birds or marine animals that might swallow it. 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. The density of a plastic sample may change due to change in crystallinity, loss of plasticizers, absorption of solvent, etc. Polyvinyl chlorideis the world's third-most widely produced syntheticplasticpolymer. You have no items in your cart. Feedback Advertising We don't save this data. 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. 0000177508 00000 n CONSTITUTION: An isotactic polyolefin powder or particle of an average particle Water's weight is one gram per cubic centimeter - a material with, for example, 1.5 specific density would then weigh 1.5 grams per cubic centimeter.

This changes the ratio for our calculation; it is now 0.945/0.74 or 1.28. 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.

Materials with an index between 1.53 and 1.57 are sometimes considered mid-index, while 1.58 and greater is considered high-index. For example, polypropylene has a density of approximately 0.90, whereas PET has a density of approximately 1.40. 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. 0000124314 00000 n Cookies are only used in the browser to improve user experience. 0000006688 00000 n When the plastic that expanded beyond the container is removed we now find that the remaining cube of heated plastic inside the container weighs only 0.933 grams. For PS the melt density is 0.945 g/cm 3 and for PP it is about 0.74 g/cm 3. Polyamide In recent years, the use of these resins has been controversial: the basis of this controversy is their leaching that, occurring at high temperature, releasesbisphenol A, a compound that is on the list of potential environmental hazardous chemicals. For convenience's sake, we have converted the specific gravities provided by the manufacturers of our products to grams per cubic centimeters.
