The specific gravity of a substance is a comparison of its density to that of water. 0000005946 00000 n 0000102892 00000 n AddThis use cookies for handling links to social media. 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. Though some manufacturers use grams per cubic centimeter to indicate the weight of their products, others merely provide the specific gravity of their material. We are still (just barely) within our 8-oz barrel capacity, but unfortunately Mr. Murphy is still lurking. It is common to use the As usual, remember to opt for reusable alternatives to plastic, to avoid purchasing the dangerous types and recycle as much as possible the types of plastic that you can! 0000127802 00000 n 0000004768 00000 n This may also be referred to as relative density. Lubrication Data Apps ASTM D792 Specific gravity, 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. 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. The best-known plastics of this group are polycarbonates(PC) used to build strong,toughproducts. 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. Description: This 3/8" OD x .062" Wall Yellow Polyethylene Tubing has a working pressure of 120 PSI @ 72F. If you are interested in knowing more about what we do, click here.

PVC 1.37-1.39 Technical name - High-Density Polyethylene its an incredible resistant resin used for grocery bags, milk jugs, recycling bins, agricultural pipe, but also playground equipment, lids, and shampoo bottles among others. 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- The ratio of the weight of the molded piece as compared to the weight of an equal volume of water ASTM D792. Now we need a minimum of 6.16 x 1.28 or 7.88 oz of shot capacity. The purpose was to provide a consistent national system to facilitate recycling of post-consumer plastics." Design & Manufacturability WebSince the density of a fluid varies with temperature, specific gravities must be determined and specified at particular temperatures. 0000015048 00000 n I'm Gelson Luz, mechanical engineer, welding specialist and passionate about: I am building this blog to be the best learning blog about engineering! 0000173991 00000 n 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. Physics 1 gallon of water weighs 8.33 lbs. 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. 0000142860 00000 n respect to the website or the information, products, services, or related graphics contained on the website for any purpose. One of the ASTM test methods for plastic commonly seen on data sheets is the test for Density and Specific Gravity (SG). 0000156682 00000 n xb```f`g`g`0cb@ !V6C'``D&yY(J-Ftt@UJ `H Dvp48(kha``aAA8koxD(lb'ftb~ef.aS-`0`"#a(1&' .8ffgS D!f' 0000142018 00000 n WebThe 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. Finishing and Plating ?qbC2]2F 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. 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. Plastics that belong to group number one are made out ofpolyethylene terephthalate or PET. Specific Gravity = (Weight A / Weight B) Density = (Weight A / Weight B) * 0.9976 g/cm3 And The SI unit is Kg/m3. Therefore, the specific gravity is a unitless number. 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.

In the next blog post, we will explain which of these plastic types can be recycled and which not, so stick around! If plastic cannot be identified in the six types above-mentioned, then it will be included in group number 7. 0000172297 00000 n The lower the density or SG of a particular material, the more material per pound or surface area you will get. 0000019679 00000 n : The units cancel out in the ratio. 0000005504 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. warranties of any kind, express or implied, about the completeness, accuracy, reliability, suitability or availability with For example, some types of plastic are reusable and others arent because of the chemicals they contain; some can be recycled and others need to be disposed of in a different way.

Polyamide Engineering Book Store 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. 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. A Specific Gravity of less than 1 means that the Used in plastic bags,six-pack rings, various containers, dispensing bottles, and most famously for plastic wraps, is not often recycled through curbside programs. So, keep reading! The specimen is weighed first in air (Weight A), and then weighed when immersed in distilled water at 23C (Weight B).
