Find out the composition and uses of commonly used plastics like thermocol, PVC and PET.

i. Thermocol:

Thermocol is also called as polystyrene and it is obtained by the polymerization of phenylethylene. The reaction is as follows:

It is used for making kitchen utensils, measuring cups, packing material etc.

ii. PVC:

It is made from the polymerization of vinyl chloride. The reaction is as follows:

It is widely used in plumbing materials, raincoats, imitation leather, electrical cable insulation etc.

iii. PET:

PET is manufactured by the condensation polymerization reaction between ethylene glycol and terephthalic acid. The reaction is as follows:

It is used in clothing, containers for liquids, packing trays, a substrate for solar cells etc.
