It holds the number one spot because of its widespread utility. Specific gravity and density are especially relevant because plastic is sold on a cost per pound basis and a lower density or specific 3t6/8lM2-lA WebThough some manufacturers use grams per cubic centimeter to indicate the weight of their products, others merely provide the specific gravity of their material. It is a very inexpensive resin per unit weight and easy to create, for these reasons it can be found everywhere: from beverage cups, insulation, packing materials to egg cartons and disposable dinnerware. LDPE 0.91-0.93 As usual, remember to opt for reusable alternatives to plastic, to avoid purchasing the dangerous types and recycle as much as possible the types of plastic that you can! This information can be used to tell whether plastic There are two basic test procedures to determine the density of a material method A, used for testing solid plastics in water, and method B, used for testing solid plastics in a liquid other than water.

The standard test method for the determination of density and specific gravity If plastic cannot be identified in the six types above-mentioned, then it will be included in group number 7. 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. Fluids Flow Engineering Therefore, the specific gravity is a unitless number. If you want to promote your products or services in the Engineering ToolBox - please use Google Adwords. 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. 0000124825 00000 n Therefore, the specific gravity (which is dimensionless) for a liquid has the same numerical value as its density in units of g/cm3. For convenience's sake, we have converted the specific gravities provided by the manufacturers of our products to grams per cubic centimeters. Hi! 0000144583 00000 n or in connection with, the use of this information. 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.

Polyamide The specific gravity of a substance is a comparison of its density to that of water. ASTM D792 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.
