Question: 1 / 650

How can plastics be identified?

By checking the color of the material

There are visible symbols embossed on the part's reversed side

Identifying plastics can be effectively done through the visible symbols embossed on the part's reversed side. These symbols are known as resin identification codes and are typically found on many plastic items. They help in discerning the type of plastic used, which is essential for recycling, repair, and proper handling processes. Each code corresponds to specific properties and characteristics of the plastic, aiding professionals in making informed decisions.

Other methods, such as performing a flame test or measuring density, can be useful but may not be practical for quick identification in a variety of settings. Additionally, checking the color of the material is not a reliable identifier since many plastics can be colored in similar ways or come in a wide array of shades, which does not reflect their true chemical composition.
