This thesis describes the manufacturing, processing and application of polyolefin thermoplastics. Polyolefins have become one of the most important kinds of plastics. Polyolefin resin represents about one third of all plastics sold and its application for films and containers dominate the packaging industry. The objective of this thesis is to present the various processing methods and application of polyolefin thermoplastics. Polyolefin is produced by several different processes. Conventional low density polyethylene is made by polymerizing ethylene at high pressure and high temperatures while high density polyethylene is polymerized at relatively low pressure and low temperatures. Generally all polyolefin possess excellent electrical properties, excellent resistance to water and moisture and good resistance to chemicals. They are translucent, light weight, tough and flexible material. This combination of properties makes them suitable for film, blow, and injection molded parts, flexible sheet and extruded profiles, and tubing.
