Threads & Torque Calcs It is 250 times stronger and just as clear as glass. 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. 6I&dsV.G{w+Z#Ot>wY[~JKWr#oyOIIl(RV[U|i:n0qfB#}CNs,%|PEyeTeB 0000134268 00000 n 0000156682 00000 n Since the density of a fluid varies with temperature, specific gravities must be determined and specified at particular temperatures. Heat Transfer Therefore, the specific gravity (which is dimensionless) for a liquid has the same numerical value as its density in units of g/cm3. Sponsored Links 0000132332 00000 n Copyright 2000 - 2023 United States Plastic Corporation. In fact, PET bottles arethe most widelyrecycled plasticin the world! Fun fact: because it is VERY resistant to fatigue, PP is usually used for living hinges (the thin piece ofplastic that allows a part of a product to fold or bend from 1 to 180 degrees). Polysulphone 1.24 In this next blog series we will explore ASTM tests commonly found on material data sheets for thermoplastic resins, starting with density and specific gravity. Density refers to the mass per unit volume of a material, whereas SG refers to a measure of the ratio of mass of a given volume of material at 23C to the same volume of deionized water. 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. 0000176664 00000 n 0000142860 00000 n Note: Both densities need to be in the same unit as they will cancel each other and produce SG. As far as its disposal is concerned, HDPEis accepted at mostrecyclingcenters in the world, as it is one of the easiest plastic polymers torecycle. 1, Zhongshan Rd., Dacun Township, Changhua County 515, Taiwan (R.O.C. But they can also be found on mobile phones and, more frequently, in compact-discs (CD). Density of Plastics: Technical Properties. 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. Physics Polymethylpentene 0.83 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. Plastic Corporation. 0000011164 00000 n So, keep reading! 0000157774 00000 n If you are interested in knowing more about what we do, click here. 9;-h3UR{SD bD=NSH3)0lefD}n 81 c+0!o XFu#N/? Intertek is the industry leader with employees in 1,000 locations in over 100 countries. The lower the density or SG of a particular material, the more material per pound or surface area you will get. 0000159988 00000 n LDPE 0.91-0.93 WebSpecific gravity is the ratio of the density of a substance to the density of the same volume of water. 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. AddThis use cookies for handling links to social media. One of the most remarkable features of plastic is just how greatly its features can vary from variety to variety. +hSm)/BNy-G:ipb4m(5i9 18N 2Y9 E7q!#5qnc"w2T.Cz(k4l@Ar$.n(*piE1uh%UF?x]*t4\J4j1i,/7Mq$``'> Polystyrene is the sixth type of plastic on the list and it can be solid or foamed. One of the most basic differences between varieties, however, can be found in how much they weigh. Acrylic sheeting, commonly referred to as plexiglass sheeting, is the most common alternative to traditional glass.

Therefore, the specific gravity is a unitless number. WebSimply enter the density of the material in which your are interested, select the shape from the drop-down list, enter the dimensions, then hit the Calculate button. 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. To sum up, its a no-go. Polyvinyl chlorideis the world's third-most widely produced syntheticplasticpolymer. 0000004927 00000 n 0000168199 00000 n Specific gravity is the ratio of the object's density to the density of water, i.e. The purpose was to provide a consistent national system to facilitate recycling of post-consumer plastics."

Others might see it as an important way to reduce risk or liability. WebDensity of Plastics Density is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm3. Vibration Engineering The most widely used member of the vinyl family, PVC is excellent when used for corrosion-resistant tanks, ducts, fume hoods and pipe. warranties of any kind, express or implied, about the completeness, accuracy, reliability, suitability or availability with General Fax: 860-963-1998, Understanding Your Data Sheet: Density & Specific Gravity, So youve narrowed down what material you need thanks to our. Specific . 0000014816 00000 n HGCs are far more dense than existing plasticse.g., 40% glass-filled nylon has a specific gravity (SG) of just 1.46and are weighty enough to compare with aluminum (2.7 SG), zinc (6.64), steel (7.6), and lead-antimony (11.35). 0000005721 00000 n 0000139528 00000 n
