For convenience's sake, we have converted the specific gravities provided by the manufacturers of our products to grams per cubic centimeters. Though that may seem like a simple and not particularly worthwhile distinction, any engineer worth their salt will tell you that weight is of the utmost importance when deciding whether a material is appropriate for a particular project. ps = density of the fluid or substance (kg/m3) Since the density of a fluid varies with temperature, specific gravities must be determined and specified at particular temperatures. 0000009713 00000 n 0000005504 00000 n 0000144583 00000 n warranties of any kind, express or implied, about the completeness, accuracy, reliability, suitability or availability with Now They Want Plastics To Be Heavy 0000004435 00000 n 0000163869 00000 n 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. 0000141220 00000 n Guide to Plastic Weights - Find Out How Much Each Type However, various factors can affect density such as crystallinity, loss of plasticizer or absorption of solvent. the molded piece as compared to the weight of an equal volume of water Understanding Your Data Sheet: Density & Specific 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. 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. 0000117341 00000 n One of the most remarkable features of plastic is just how greatly its features can vary from variety to variety. Web1 28768 DENSITY OF PLASTICS What is Density of plastic: The density of a substances is generally known as mass per unit volume. 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). 0000014066 00000 n If plastic cannot be identified in the six types above-mentioned, then it will be included in group number 7. 0000149107 00000 n 10XX,52,11XX,17,12XX,7,13XX,4,15XX,16,3XXX,2,40XX,10,41XX,12,43XX,5,44XX,4,46XX,5,47XX,3,48XX,3,5XXX,23,6XXX,3,71XX,1,8XXX,22,92XX,5,93XX,1,94XX,4,98XX,2,AISI,66,ASTM,172,Atomic-Mass,327,Atomic-Number,436,Atomic-Radius,86,Atomic-Symbol,329,Atomic-Volume,94,Austenitic,56,Boiling-Point,94,bp1,97,CBS,6,Chemical-Elements,100,Chemical-Symbol,217,CMDS,13,Coefficient-of-Thermal-Expansion,85,Covalent-Radius,87,Crystal-Structure,109,CS,17,CVS,3,Density,297,Duplex,6,el1,100,Elastic-Modulus,30,Electrical-Conductivity,79,Electro-Affinity,87,Electron-Configuration,109,Electronegativity,102,Electrons-per-Shell,111,Enthalpy-of-Fusion,93,Enthalpy-of-Vaporization,95,Ferritic,12,fp1,38,fs1,45,Group-Number,218,HCS,14,Heat-of-Fusion,87,Heat-of-Vaporization,85,HMCS,16,Ionic-Radius,78,Ionization-Energy,102,Ionization-Potential,101,l1,438,LCS,21,List,281,lp1,69,Martensitic,6,MCS,17,MDS,14,Melting-Point,96,mm1,2,mp1,99,MS,4,NCMDBS,6,NCMDS,31,NCS,2,NMDS,8,Oxidation-States,104,p1,44,Period-Number,107,pr1,53,Properties,40,RCLS,1,RCS,16,ref1,5,RRCLS,3,RRCS,4,SAE,201,Site,2,SMS,5,Specific-Gravity,83,Specific-Heat,92,Specific-Weight,1,SS,80,Tests,2,Thermal-Conductivity,105,tm1,274,Valence-Electrons,98,wt1,26, Materials: 2022: Specific Gravity of Plastic (& Formula, Definition, Infographic), 2022: Specific Gravity of Plastic (& Formula, Definition, Infographic), https://1.bp.blogspot.com/-qPMKZ48g6Vg/XRPSAE54r4I/AAAAAAAAOsY/VpY75KLZ6O4JJdZeUM1jyrM_g0N8xDB3QCLcBGAs/s320/specific-gravity-of%2Bplastic.webp, https://1.bp.blogspot.com/-qPMKZ48g6Vg/XRPSAE54r4I/AAAAAAAAOsY/VpY75KLZ6O4JJdZeUM1jyrM_g0N8xDB3QCLcBGAs/s72-c/specific-gravity-of%2Bplastic.webp, https://materials.gelsonluz.com/2019/07/specific-gravity-of-plastic-formula.html, Not found any post match with your request, STEP 2: Click the link on your social network, Can not copy the codes / texts, please press [CTRL]+[C] (or CMD+C with Mac) to copy, CBSE Class 10 Chemistry Chapter 2 Important Questions and Answers.

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. 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! 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.
