It comes in two basic forms: rigid and flexible. 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. Due to the different density of plastic, we can easily identify different plastics by "Buoyancy Test", for more information, please check out in related articles. It is common to use the It has the simplest structure of all the plastics, making it easy and cheap to produce. Applications and Design It is mostly used for food and drink packaging purposes due to its strong ability to prevent oxygen from getting in and spoiling the product inside. In its rigid form, PVC is largely used in the building and construction industry to produce door and window profiles and pipes (drinking and wastewater). 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.

WebSpecific gravity is the (unit less) ratio of the solid wood density to the density of water at the same temperature. Roto-molded LLDPE with thick walls for superior strength anddurability. Any reliance you place on such information is therefore strictly at your ownrisk. Web1 28768 DENSITY OF PLASTICS What is Density of plastic: The density of a substances is generally known as mass per unit volume. WebSpecific gravity is a measure of the ratio of mass of a given volume of material at 23C to the same volume of deionized water. In 1988, theSociety of the Plastics Industryintroduced the Resin Identification Code (RIC) system which divided plastic resins into 7 different categories. (You will help other colleagues find this blog). If you are interested in knowing more about what we do, click here. 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. In order to help you make better-informed decisions about the products that you buy, today we will go through the seven different types of plastic, how they differ, and their impact on the environment. 0000124655 00000 n Economics Engineering 0000149962 00000 n Polyethylene Physicists use 39.2 F (4 C) as the standard, but engineers ordinarily use 60 F.
