Abstract

A synthetic man-made material that contains different types of organic polymers having heavy molecular weight such as polyethylene, PVC etc. when it is soft, it can be easily moulded to any form. And when it turns hard, it becomes rigid or slightly elastic in nature and it is called as plastic. Plastic takes a long time to degrade because of that it is durable also, this long time to degrade is because plastic can easily resist the natural process of degradation. There are two types of plastic 1) Thermoset and 2) Thermoplastics. Thermoset plastics are that kind of plastic which once set cannot be reversed by the means of heat. Whereas thermoplastics are those which can be reversed by providing heat to it.
