The Properties of Plastics

Plastic , polymeric material that has the capability of being molded or shaped, usually by the application of heat and pressure. This property of plasticity , often found in combination with other special properties such as low density , low electrical conductivity, transparency, and toughness, allows plastics to be made into a great variety of products. These include tough and lightweight beverage bottles made of polyethylene terephthalate PET , flexible garden hoses made of polyvinyl chloride PVC , insulating food containers made of foamed polystyrene , and shatterproof windows made of polymethyl methacrylate. In this article a brief review of the essential properties of plastics is provided, followed by a more detailed description of their processing into useful products and subsequent recycling.
