Plastics Chart 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. 0000134268 00000 n %PDF-1.4 % 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. 0000173123 00000 n To figure the specific gravity of a substance take the number of pounds per gallon the substance weighs and divide it by 8. 0000144583 00000 n The specific gravity of a substance is a comparison of its density to that of water.

Thanks to its versatile properties, such as lightness, durability, and easiness of processability, PVC is now replacing traditional building materials like wood, metal, concrete, rubber, ceramics, etc. One of the most remarkable features of plastic is just how greatly its features can vary from variety to variety. For example, The American Society for Testing and Materials (ASTM), approximately a 30% density reduction from PET to PP and an increased yield on pounds purchased. Plastics that belong to group number one are made out ofpolyethylene terephthalate or PET. 0000145640 00000 n 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. Our network of more than 1,000 laboratories and offices in more than 100 countries, delivers innovative and bespoke Assurance, Testing, Inspection and Certification solutions for our customers' operations and supply chains. 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. Though some manufacturers use grams per cubic centimeter to indicate the weight of their products, others merely provide the specific gravity of their material. 0000160831 00000 n Other custom sizes of trays, special partitions, flanges, outlets, etc. It has a durometer of 50 D, a tensile strength of 1600 PSI, a brittleness temperature of -76F, a specific gravity of .921, and an elongation at break.

Finish: Solid. The standard test method for the determination of density and specific gravity Solids and Metals - Specific Gravities . Specific gravity for some common solids and metals like aluminum, asbestos, brass, calcium and many others . Sponsored Links . The Specific Gravity - SG- is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. Environmentally-speaking its among the worst types of plastic: first, it is regarded as notbiodegradable. Plastic Material: Density & Specific Gravity - Ji-Horng Health effects vary depending on the resin and plasticizers in this plastic that often For convenience's sake, we have converted the specific gravities provided by the manufacturers of our products to grams per cubic centimeters. 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. Design & Manufacturability One of the ASTM test methods for plastic commonly seen on data sheets is the test for Density and Specific Gravity (SG). In addition, polystyrene is not accepted incurbside collectionrecycling programs and is not separated and recycled where it is accepted.

Lubrication Data Apps 0000125208 00000 n SPECIFIC GRAVITY- The ratio of the weight 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. Because of this difference, when comparing polypropylene sheet to PET sheet, holding constant gauge and size, customers can see approximately a 30% density reduction from PET to PP and an increased yield on pounds purchased. WebThough some manufacturers use grams per cubic centimeter to indicate the weight of their products, others merely provide the specific gravity of their material. 1, Zhongshan Rd., Dacun Township, Changhua County 515, Taiwan (R.O.C. Second, polystyrene foam blows in the wind and floats on water, due to its low specific gravity. Moreover, the decomposition of BPA in landfills does not occur meaning that this chemical will be persistent in the ground and will eventually find its way into water bodies contributing to aquatic pollution.

Tensile yield strength is the maximum engineering stress in psi (or Pa) at which a permanent non-elastic deformation of the thermoplastic material begins. The specimen is weighed first in air (Weight A), and then weighed when immersed in distilled water at 23C (Weight B). 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.

The lower the density or SG of a particular material, the more material per pound or surface area you will get. Some manufacturers may consider testing and certification an obstacle to overcome to get to market. Also, it is relatively hard and resistant to impact and can be subjected to temperatures of up to 120 C without being affected. Description: This 3/8" OD x .062" Wall Yellow Polyethylene Tubing has a working pressure of 120 PSI @ 72F. And The SI unit is Kg/m3. Put theplastic specific gravityin perspective! 0000132332 00000 n 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). A Specific Gravity of less than 1 means that the Styrene-butadiene 0.93 It is a very inexpensive resin per unit weight and easy to create, for these reasons it can be found everywhere: from beverage cups, insulation, packing materials to egg cartons and disposable dinnerware.

LDPE is used for the infamous plastic bags that are usually used for a few seconds and then discarded. Specific gravity (S.G.) is a measure of the relative density of a substance as compared to the density of water at a standard temperature. If plastic cannot be identified in the six types above-mentioned, then it will be included in group number 7. 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. On top of this, plastics number 7 is almost never recycled.
