Thermoplastics and thermosets are the two basic categorizations of plastic. Thermoplastics can be melted and molded repeatedly. This plastic is typically brought to manufacturers in the form of pellets. Thermosets cannot be reformed once they become a solid. This plastic is brought to manufacturers in liquid and powder forms.
Most plastics are a combination of both types. Below is a list of the most common plastic compounds, with an example of each.
