Why is polythene called thermoplastic?
Polythene is also known as polyethylene. Polythene is a type of plastic that is widely used in packaging and many of the plastic products we use today. You see polythene in all shapes and sizes. Polythene is such a widely used product because it is easy to bend it and mold it into the shape that you want. This action of molding the plastic is called thermosetting. Polythene is heated to high temperatures and molded into the shape that is desired. Then the object is set aside and cooled. Once the object is at room temperature (or close to it) the object will not break or bend so readily. Now, if you take the prefix of thermosetting you just have "thermo." Thermo is typically used with words meaning temperature or heat. Because polythene is a plastic and it can be set in its shape by heat, it is called thermoplastic.
