Identification and Separation of Waste Plastics

There are many types of polymer materials, and the patterns are also varied. There are many different names and come from different industries. Plastics can be divided into thermoplastic and thermosetting polymer materials according to their structure and performance. Thermoplastic polymers are soluble, Fusible; thermosetting polymer material is insoluble and infusible; therefore, the method of heating and dissolving can be used to distinguish between its thermoplastic and thermal-induced polymer materials. There are many methods to identify polymer materials. The most common simple method is: appearance identification method. Dissolve identification method. Burning identification method, density identification method and other methods.
