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. This test is often seen with the designation ASTM D792. 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. This information can be used to tell whether plastic will float (or sink) if dropped in water (Buoyancy). Heres a brief recap of what we have learned so far: We hope this blog post has provided some clarity about the differences among all these plastic types. 0000169321 00000 n Description: This 3/8" OD x .062" Wall Yellow Polyethylene Tubing has a working pressure of 120 PSI @ 72F.

Specific gravity (S.G.) is a measure of the relative density of a substance as compared to the density of water at a standard temperature. 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. +74|=8/[ dcepJ@@ Q endstream endobj 8 0 obj<> endobj 10 0 obj<> endobj 11 0 obj<>/Font<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI]>> endobj 12 0 obj[278 750 474 750 750 750 750 238 750 750 750 750 278 750 278 278 556 556 556 556 556 750 750 750 556 750 750 750 750 750 750 611 750 722 750 722 722 667 611 778 722 278 750 750 750 750 722 778 667 750 722 667 611 750 667 944 750 667 750 750 750 750 750 750 750 556 611 556 750 556 333 611 750 278 750 750 278 750 611 611 611 750 389 556 333 611 556 750 556 556] endobj 13 0 obj<> endobj 14 0 obj<> endobj 15 0 obj<> endobj 16 0 obj<> endobj 17 0 obj<> endobj 18 0 obj[/ICCBased 39 0 R] endobj 19 0 obj[278 750 355 750 750 750 750 191 333 333 389 750 278 333 278 278 556 556 556 556 556 556 556 556 556 556 278 750 750 584 750 556 750 667 667 722 722 667 611 750 722 278 750 667 556 833 722 778 667 750 722 667 611 722 667 944 750 750 750 750 750 750 750 750 750 556 556 500 556 556 278 556 556 222 222 500 222 833 556 556 556 556 333 500 278 556 500 722 500 500] endobj 20 0 obj<> endobj 21 0 obj<> endobj 22 0 obj[278 750 750 750 750 750 750 750 333 333 750 750 750 750 278 278 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 722 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 750 556 750 500 556 556 278 556 556 222 750 750 222 833 556 556 556 750 333 500 278 556 500 750 750 500] endobj 23 0 obj[250 778 778 778 778 778 778 778 778 778 778 778 778 778 778 778 778 500 500 778 778 778 778 778 778 778 778 778 778 778 778 778 778 778 778 667 778 778 778 778 778 778 778 778 778 778 778 778 778 778 778 778 778 778 778 778 778 722 778 778 778 778 778 778 778 444 500 444 500 444 778 778 778 278 778 778 278 778 500 500 778 778 333 389 278 778 500] endobj 24 0 obj<> endobj 25 0 obj<> endobj 26 0 obj<>stream Continue reading to learn more!

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. 1 gallon of water weighs 8.33 lbs. Portions throughout the same sample may also differ in density due to differences in crystallinity, thermal history, porosity, or changes to the material composition, such as the addition of a filler or pigment. If plastic cannot be identified in the six types above-mentioned, then it will be included in group number 7.

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. 0000126937 00000 n Styrene-butadiene 0.93 Machine Design Apps Polyethylene Since the density of a fluid varies with temperature, specific gravities must be determined and specified at particular temperatures.

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. 0000051762 00000 n In 1988, the Society of the Plastics Industry introduced the Resin Identification Code (RIC) system which divided plastic resins into 7 different categories.
