What are the 2 main types of plastic?

There are two main types of plastics and these are named Thermoplastics and Thermosetting Plastics. Thermoplastics are made up of lines of molecules with few cross linkages. This allows them to soften when heated and to be bent into a variety of shapes and forms.
