Quizplus · Accepted Answer

The two major types of plastic are thermoplastic and thermosets. Thermoplastics can be melted and reformed multiple times, while thermosets cannot be melted again once they have been molded or cured. Celluloid and elastomers are subcategories of thermoplastics and do not constitute the two major types.
