Hi...

Plastics can be classified into two types based on the changes that occur while heating..

Thermoplastic-Plastic that gets softened on heating and hardened on cooling is thermoplastic..eg.Polythene-For the manufacture of packets,tubes,containers...Poly vinyl chlroride(pvc)-Manufacturer of plumbing,shoes,electrical wiring.....

Thermosetting plastic-The plastic which remains soft when heated during its manufacture,and gets hardened permanently on cooling is thermosetting plastic......eg.Bakelite-manufacturer of plug,switch.......Melamine formal dehyde resin-manufacture of unbreakable crockery...
