- There are two main types of plastics –. Thermoplastics which are softened by heat and can be moulded. (Injection moulded, blow moulded or vacuum formed). Good examples are acrylic, polypropylene, polystyrene, polythene and PVC. Thermosets which are formed by ha heat process but are then set (like concrete) and cannot change shape by reheating.

- Smart Plastics Guide Plastic products are typically labeled with a number surrounded by the recycling symbol. These numbers and labels identify both the type of resin used to make the plastic and the products recyclability. Associated with the different types of resin are potential health risks. The following table summarizes seven different types of commonly used plastics, product examples, recyclability, and potential health risks.

What would be the advantages and disadvantages be of using Arylic (plastic) for the chimes on windchimes? What is Acrylic? Acrylic is a useful, clear plastic that resembles glass, but has properties that make it superior to glass in many ways. Common brands of high-grade acrylic include Polycast, Lucite and Plexiglass. There are two basic types of acrylic: extruded and cell cast. Extruded or continuous cast acrylic is made by a less expensive process, is softer, can scratch easier and may contain impurities.

- Addition Polymers. Addition polymers such as polyethylene, polypropylene, poly(vinyl chloride), and polystyrene are linear or branched polymers with little or no cross-linking.As a result, they are thermoplastic materials, which flow easily when heated and can be molded into a variety of shapes.olyethylene has no taste or odor and is lightweight, nontoxic, and relatively inexpensive. It is used as a film for packaging food, clothing, and hardware. Most commercial trash bags, sandwich bags, and plastic wrapping are made from polyethylene films.
