Contrary to HDPE, LDPE is characterized by low-density molecules, giving this resin a thinner and more flexible design. 0000175797 00000 n Polymers typically have a benchmark density that can offer an approximate value of what the density of a particular material can be expected to be. 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). 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. Others might see it as an important way to reduce risk or liability. Chart 0000006688 00000 n 0000006323 00000 n 0000004768 00000 n The lower the density or SG of a particular material, the more material per pound or surface area you will get. 9;-h3UR{SD bD=NSH3)0lefD}n 81 c+0!o XFu#N/? 0000153750 00000 n Materials and Specifications 0000159988 00000 n Join our movement of Global Change Agents to receive exclusive invitations and updates. 0000016671 00000 n In the next blog post, we will explain which of these plastic types can be recycled and which not, so stick around! LDPE is used for the infamous plastic bags that are usually used for a few seconds and then discarded. in various applications. In fact, not only can plastic be found in a variety of different shapes and colors, but also in many different types. 0000166558 00000 n 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. 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.

. 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. Civil Engineering 0000129490 00000 n These specialty materials have densities of up to 15 g/cc yet still have the moldability of plastics. This may also be referred to as relative density.

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. 0000004927 00000 n **Ji-Horng Plastic is a leading plastic injection molding manufacturer since 1986, for more information, please contact us!**. To figure the specific gravity of a substance take the number of pounds per gallon the substance weighs and divide it by 8. or damage, or any loss or damage whatsoever arising from loss of materials, time or profits arising out 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. And The SI unit is Kg/m3. 7 0 obj<> endobj xref 7 103 0000000016 00000 n Also, it is relatively hard and resistant to impact and can be subjected to temperatures of up to 120 C without being affected. The specimen is weighed first in air (Weight A), and then weighed when immersed in distilled water at 23C (Weight B). In recent years, the use of these resins has been controversial: the basis of this controversy is their leaching that, occurring at high temperature, releasesbisphenol A, a compound that is on the list of potential environmental hazardous chemicals. In order to help you make better-informed decisions about the products that you buy, today we will go through the seven different types of plastic, how they differ, and their impact on the environment. WebMinerals and other Materials - Specific Gravities Specific gravities for minerals and other materials. ,unv . Since the density of a fluid varies with temperature, specific gravities must be determined and specified at particular temperatures. The specific gravity of a substance is a comparison of its density to that of water. 0000134268 00000 n
