Plastics have a really wide specific gravity range depending on its composition. %PDF-1.4 % To figure the specific gravity of a substance take the number of pounds per gallon the substance weighs and divide it by 8. Polyacronitrile 1.17 0000042285 00000 n Some elements may not work properly. It is 250 times stronger and just as clear as glass. "Density" has its own unit of measurement, 1 g/cm3 or 1 kg/m3, in contrast, specific gravity has no unit of measurement goes with it; nevertheless, although they don't have the same meaning, they have the same value because density of water is quite close to 1g/cm3. Civil Engineering or in connection with, the use of this information. 0000152962 00000 n ), Copyright 2000 - How about an incentive to share this post? Solids and Metals - Specific Gravities . Specific gravity for some common solids and metals like aluminum, asbestos, brass, calcium and many others . Sponsored Links . 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. WebSupplier: U.S.

Vivak Sheet has become a staple in the point-of-purchase industry due to its economic advantages compared to polycarbonate and superior impact strength over acrylic. SPECIFIC GRAVITY- The ratio of the weight of the molded piece as compared to the weight of an equal volume of water ASTM D792. 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). 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. At Plastics For Change, we are giving second life to discarded plastic numbers 1,2,4, and 5 and re-use them for the creation of various different products while cleaning our oceans! Urine normally has a specific gravity between 1.003 and 1.035. 0000016671 00000 n 0000004599 00000 n 0000167357 00000 n Polyvinyl acetate 1.19 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.

Density measures the mass per unit volume. It is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm 3. The density of a plastic sample may change due to change in crystallinity, loss of plasticizers, absorption of solvent, etc. Because its made with long unbranched polymer chains its much stronger and thicker than PET.

In 1988, theSociety of the Plastics Industryintroduced the Resin Identification Code (RIC) system which divided plastic resins into 7 different categories. For PS the melt density is 0.945 g/cm 3 and for PP it is about 0.74 g/cm 3. 0000005721 00000 n 0000018128 00000 n 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. The American Society for Testing and Materials (ASTM) is an organization that defines and sets standards to ensure good quality and workmanship. In addition, polystyrene is not accepted incurbside collectionrecycling programs and is not separated and recycled where it is accepted. You have no items in your cart. It comes in two basic forms: rigid and flexible. Join our movement of Global Change Agents to receive exclusive invitations and updates. the molded piece as compared to the weight of an equal volume of water 0000166558 00000 n Specific GravityDensity and specific gravity sound quite similar, some even say that they are synonyms; however, they are actually not the same, below we are going to introduce the differences of them.What's the meaning of "Density"?Density ismass or weight of a substance per unit volumeundernormal temperature and pressure. The standard test method for the determination of density and specific gravity Therefore, the specific gravity (which is dimensionless) for a liquid has the same numerical value as its density in units of g/cm3.

The solid wood density may be determined using the green volume, 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. PA-12 1.02 Description: This 3/8" OD x .062" Wall Yellow Polyethylene Tubing has a working pressure of 120 PSI @ 72F. 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. 0000157774 00000 n We are still (just barely) within our 8-oz barrel capacity, but unfortunately Mr. Murphy is still lurking. Friction Formulas Apps 0000015048 00000 n Blood normally has a specific gravity of ~1.060. Some manufacturers may consider testing and certification an obstacle to overcome to get to market.
