High-Density Polyethylene, Number Two (HDPE).

What are the 7 types of plastic?ħ different kinds of plastic 1 Polymer Made of Polyethylene Terephthalate (PETE or PET). Working with examples that are already familiar is the most effective technique to gain knowledge.However, if a known sample isn’t accessible, you may occasionally figure out the essentials of the sort of plastic you have on hand by utilizing your nose and an open flame.This is called olfactory analysis.Hold a little piece of the plastic material to the edge of the flame in a careful manner until it starts to burn.Take all necessary measure to ensure your safety. How can I determine what type of plastic material I have? The use of Fourier Transform Infrared Spectroscopy (FTIR), which is used for qualitatively and quantitatively determining the presence of specific chemical groups, such as C=O, or C-H, or C-CH3 in a plastic material, is a method that is considered to be a more scientific approach to the identification of plastic. The identification of the kind of plastic based on its density, also known as gravity dressing, is a straightforward approach that may be used to differentiate between the many forms of plastic.The density of individual types and variations of plastics can vary greatly.The different densities of the various types of plastics may thus be used to determine whether or not they float or sink in water by observing how they behave in such environments.
