Question

What are the uses of plastics

Answer 1

Plastics are polymeric materials having good tensile strength. These are extremely versatile material and have wide range of industrial and other applications

Complete step by step solution:
Plastics are polymeric materials having good tensile strength and rigidity. They have properties intermediary to elastomeric and fiber forming polymers. These materials can either be fully amorphous or partially crystalline. Plastics are a group of Synthetic or Semi-Synthetic material used for a range of applications. The row products used to produce plastics are natural products such as Coal, Cellulose, Natural gas, Crude oil. The term plastic derives from a Greek word Plastikos, meaning fit for molding.These are extremely versatile materials and have a wide range of industrial and other applications. They have relatively low density. So, they have the advantage of light weight. Plastic can be made to conduct when required. Another property is they are corrosion resistant materials that they can resist the attack of other substances. This property makes them durable. These are suitable for use in harsh environments. They can be molded into different shapes. And are transparent can be used in optical devices. Durability of plastic can be used for the application such as window frames and pipes.They provide insulation from cold and heat, preventing energy leakage. Plastics are used in the building and construction industry. Plastics are used in Orthopedic devices. People with severely impaired hearing can have plastic implants that bring sound back in their hearts. Artificial cornea can be made by using plastic.Plastics are highly flexible as compared to metals. They are cheaper than metals. Their durability is high so they can last for a long period of time. They can be used to store water in Plastic bottles and chemicals in Chemical Laboratories. This is because they are non-reactive with water and air.

Note: There are two types of plastics including thermosetting plastic and Thermoplastics. Thermosetting plastic can retain shapes but can not return to their original form. Example: Bakelite. Thermoplastics can be molded and remolded again and again. Example is Acrylonitrile butadiene styrene.
