Each one is different from the other and has different uses. 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. It has the simplest structure of all the plastics, making it easy and cheap to produce. 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! in various applications. 0000137613 00000 n So, keep reading! Though some manufacturers use grams per cubic centimeter to indicate the weight of their products, others merely provide the specific gravity of their material. Polystyrene 1.05 POM 1.41-1.43 0000005721 00000 n A Specific Gravity of less than 1 means that the 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).

Electronics Instrumentation Method A is the more common test method used, and can be performed with sheet, rod, tube and molded pieces of plastic materials that are not affected by water. 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. used for pressurized water systems - sprinkler.. highly resistant to acids, bases and many solvents, resistant to a variety of acids and bases, may be damaged by some solvents and chlorinated hydrocarbons, usable for water, gas and drainage systems, similar to PVC - but designed for water up to, resistant to abrasion, acids, bases, solvents and much more.
