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. This information can be used to tell whether plastic will float (or sink) if dropped in water (Buoyancy). Specific gravity, ABS 1.04-1.07 i.e. 0000167357 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. Plastic Corp. carries an excellent selection of spray bottles perfect for cleaning. Example: A gallon of oil weighs 9.5 lbs per gallon9.5 lbs / 8 = 1.187 specific gravity. Polystyrene is the sixth type of plastic on the list and it can be solid or foamed.

Specific gravity, generally speaking, measures the density of an object as compared to water. In no event will we be liable for any loss or damage including without limitation, indirect or consequential loss This may also be referred to as relative density. 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. For convenience's sake, we have converted the specific gravities provided by the manufacturers of our products to grams per cubic centimeters. 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.

Ultimate tensile strength is the maximum stress the thermoplastic material can withstand before failing, whichever occurs at the higher stress level. However, various factors can affect density such as crystallinity, loss of plasticizer or absorption of solvent. But if youre new to the industry, or dont work in a technical role, the information stated on material data sheets can leave you more confused than when you started. Tensile yield strength is the maximum engineering stress in psi (or Pa) at which a permanent non-elastic deformation of the thermoplastic material begins.
