Hard and sturdy, it can withstand high temperatures and is found in tupperwares, car parts, thermal vests, yogurt containers, and even disposable diapers. 0000005946 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. 0000173991 00000 n 0000170169 00000 n Science based targets for a Global Plastics Treaty, Plastics For Change is now an Ocean Bound Plastic certified collector, efforts made by the plastic industry to increase its reusability, market is forecasted to grow even more in the following years, For Brands - Click Here to Source with Purpose. 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. 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. The information contained in this article is for general information purposes only. But they can also be found on mobile phones and, more frequently, in compact-discs (CD). For convenience's sake, we have converted the specific gravities provided by the manufacturers of our products to grams per cubic centimeters. 0000018128 00000 n How about an incentive to share this post? Welding Stress Calculations Mass Versus 0000006688 00000 n You have no items in your cart. Training Online Engineering. 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. One of the most basic differences between varieties, however, can be found in how much they weigh. Polyethylene 0000004435 00000 n Polypropylene 0.90-0.92 0000008409 00000 n (You will help other colleagues find this blog). 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. %PDF-1.4 % The most widely used member of the vinyl family, PVC is excellent when used for corrosion-resistant tanks, ducts, fume hoods and pipe. Some manufacturers may consider testing and certification an obstacle to overcome to get to market. 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.

This may also be referred to as relative density. Fluids Flow Engineering The specimen is weighed first in air (Weight A), and then weighed when immersed in distilled water at 23C (Weight B). Specific Gravity (SG) is defined as the ratio of Pressure Vessel 0000163869 00000 n First, we have to know that the formula of density is: As formula shown, density is total mass of the object divided by total volume of object, which means: 1 gram per cubic centimetre or 1 kilogram per cubic metre.Density of water is1 gram per cubic centimeter (1 g/cm3), but actually, the exact density of water is not really 1 g/cm3, but rather a bit less (very, very little less) than 1, so we can say thatgenerally the weight and volume of water is the same.What's the meaning of "Specific Gravity"?Specific Gravity means specific value of an object undernormal temperature and pressure. ASTM D792 Engineering Book Store LDPE 0.91-0.93 Contrary to HDPE, LDPE is characterized by low-density molecules, giving this resin a thinner and more flexible design.
