Answer.
plastics are divided into two types:
1. thermoplastics
plastics which easily get deformed(become soft) on heating and can be bent easily are known as thermoplastics.
these can be moulded into different shapes again and again by repeated heating and cooling.
examples. polythene, polystyrene..
2.thermosetting plastics
plastics which once moulded into a shape do not become soft on heating and cannot be moulded again are called thermosetting plastics.
these maintain their shapes and size at high temperature also.
examples. bakelite, formica
