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. Engineering Forum I'm Gelson Luz, mechanical engineer, welding specialist and passionate about: I am building this blog to be the best learning blog about engineering! 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. This information can be used to tell whether plastic In 1988, theSociety of the Plastics Industryintroduced the Resin Identification Code (RIC) system which divided plastic resins into 7 different categories. 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. However, various factors can affect density such as crystallinity, loss of plasticizer or absorption of solvent. Despite its many advantages and efforts made by the plastic industry to increase its reusability, PVC is still hardly recyclable and should therefore be avoided, whenever possible. The purpose was to provide a consistent national system to facilitate recycling of post-consumer plastics." 0000125208 00000 n 0000124088 00000 n Polypropylene 0.90-0.92 To figure the specific gravity of a substance take the number of pounds per gallon the substance weighs and divide it by 8. 0000004265 00000 n The standard test method for the determination of density and specific gravity It holds the number one spot because of its widespread utility.
