Expanded PVC sheet plastic is the ideal material where durable construction materials are needed. For convenience's sake, we have converted the specific gravities provided by the manufacturers of our products to grams per cubic centimeters. 0000015222 00000 n Heat Transfer Materials with an index between 1.53 and 1.57 are sometimes considered mid-index, while 1.58 and greater is considered high-index. Put theplastic specific gravityin perspective! 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.

In fact, not only can plastic be found in a variety of different shapes and colors, but also in many different types. Polypropylene is the second-most widely producedcommodity plastic and its market is forecasted to grow even more in the following years. Total elongation at failure of some polymers: Tensile modulus or Young's Modulus is the ratio of stress to strain within the elastic region of the stress-strain curve before the yield point. 0000149962 00000 n 0000016671 00000 n 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. Other custom sizes of trays, special partitions, flanges, outlets, etc. How about an incentive to share this post? To figure the specific gravity of a substance take the number of pounds per gallon the substance weighs and divide it by 8. ?qbC2]2F This broad range of flexible Tygon tubing products are engineered to meet many user specifications including chemical resistance, fluctuations in temperature, abrasion, high purity and long servicelife. WebSupplier: U.S. used for pressurized water systems - sprinkler.. highly resistant to acids, bases and many solvents, resistant to a variety of acids and bases, may be damaged by some solvents and chlorinated hydrocarbons, usable for water, gas and drainage systems, similar to PVC - but designed for water up to, resistant to abrasion, acids, bases, solvents and much more. i.e. 0000002775 00000 n Manufacturing Processes If you are interested in knowing more about what we do, click here. Specific Gravity means specific value of an object under normal temperature and pressure. ,unv . Others might see it as an important way to reduce risk or liability. SPECIFIC GRAVITY- The ratio of the weight of 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.

But they can also be found on mobile phones and, more frequently, in compact-discs (CD). This bucket is economically priced, while still featuring premium bucket quality and durability. Mechanical Tolerances Specs This may also be referred to as relative density. Polyvinyl acetate 1.19 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. 0000086690 00000 n ABS 1.04-1.07 It holds the number one spot because of its widespread utility. Helium gas has a density of 0.164g/liter It is 0.139 times as dense as air . 1, Zhongshan Rd., Dacun Township, Changhua County 515, Taiwan (R.O.C. Physics Urine normally has a specific gravity between 1.003 and 1.035. 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. 0000145640 00000 n 0000143715 00000 n Plastic Corp. carries an excellent selection of spray bottles perfect for cleaning. 0000160831 00000 n 0000002716 00000 n WebSpecific Gravity - SG - Tensile Yield Strength - y-(10 3 psi) Tensile Modulus - E - (10 3 psi) Coefficient of Linear Expansion - - (10-6 in/in o F) Thermal Conductivity - k - (Btu in Since the density of a fluid varies with temperature, specific gravities must be determined and specified at particular temperatures. 0000169321 00000 n 0000125957 00000 n Not all plastic is born equal. It is mostly used for food and drink packaging purposes due to its strong ability to prevent oxygen from getting in and spoiling the product inside. That value must be known in order to determine the overall weight of said project and whether its other components will be able to support the heft of the plastic component - which is why we've put together this quick and easy guide on the weights of some of our most popular plastics. Copyright 2000 - 2023 United States Plastic Corporation. Ultimate tensile strength is the maximum stress the thermoplastic material can withstand before failing, whichever occurs at the higher stress level. Fun fact: because it is VERY resistant to fatigue, PP is usually used for living hinges (the thin piece ofplastic that allows a part of a product to fold or bend from 1 to 180 degrees). Threads & Torque Calcs It has the simplest structure of all the plastics, making it easy and cheap to produce. Please read Google Privacy & Terms for more information about how you can control adserving and the information collected. 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). It is common to use the 0000156682 00000 n Therefore, the specific gravity (which is dimensionless) for a liquid has the same numerical value as its density in units of g/cm3. Specially designed for marine applications, antiskid HDPE sheeting offers superior durability with the additional benefit of a non-skid surface perfect for high-traffic marine surfaces. Training Online Engineering. Despite its many advantages and efforts made by the plastic industry to increase its reusability, PVC is still hardly recyclable and should therefore be avoided, whenever possible. 0000006688 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. 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). 2023, by Engineers Edge, LLC www.engineersedge.com 7 0 obj<> endobj xref 7 103 0000000016 00000 n WebDensity of Plastics Density is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm3. 0000173123 00000 n 0000125208 00000 n WebMaterial density g/cc 1 g/cc = material density = specific gravity Therefore, knowing the specific gravity and with the help of the handy conversion table on the shared drive one 0000140352 00000 n Power Transmission Tech. 0000142018 00000 n 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. 0000164707 00000 n 0000136804 00000 n 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. 6, Sec. 6I&dsV.G{w+Z#Ot>wY[~JKWr#oyOIIl(RV[U|i:n0qfB#}CNs,%|PEyeTeB You can target the Engineering ToolBox by using AdWords Managed Placements.
