Plastic Industry

Plastic Industry Across The World

Even plastic make contaminate to our land but plastic industries are highly develop in many countries over the world. People become dependent to the availability of plastic even car body also made from plastic not use metal anymore. 

The development of plastics from laboratory curiosities to product tailored to industry's need has brought new and economical materials of construction to the engineer and the designer. Not only can plastic replace, metals and other materials, but they can also be used with them. A plastic may be defined as a material that contains a polymerized organic substance of large molecular weight as an essential ingredient, is solid in its finished state, and some stage in its manufacturer or its processing into finished articles can be shaped by flow.

The common basic materials are coal, petrochemicals, cotton, wood, gas, air, salt and water. Plastic lend themselves to exceedingly large number of application because of their toughness, water resistance, excellent resistance to corrosion, ease of fabrication, and remarkable color range.

The use of plastic material for a specific application is dependent upon its composition, its particular properties, and the design of the part. Synthetic resins are the large source of plastic, with cellulose derivative ranking next. All plastic materials of construction have limitation, but, when properly selected, they can be used with the same degree of assurance as metals and alloys.
