Synthetic Resins and Plastics

Abstract

Plastic (adj.) is defined by Webster [1] as “capable of being molded or modeled (e.g., clay) … capable of being deformed continu-ously and permanently in any direction with-out rupture.” Plastic (n.) is a plastic substance, specifically, any of numerous organic synthetic or processed materials that are mostly thermoplastic or thermosetting polymers of high molecular weight and that can be made into objects, films, or filaments.
