The plastics we use in our lifestyle also are made from polymers. All plastics do not have an equivalent sort of arrangement of units.
In some, the arrangement of a monomer is linear, and in others, the arrangement is cross-linked.
Counting on the sort of arrangement, we have two main sorts of polymers - thermoplastics and thermoset. The below image represents the chain type in both the plastics and the force of attraction between them.

Types of plastics

 Thermoplastics:

Crushed plastics for recycling
  • These are plastics that deform their shape on exposure to heat. i.e. is these plastics can be reused by heating and can be moulded into different shapes.
  • Thermoplastics are flexible in nature.
  • These are expensive, softens when heated and are weak in nature.
  • It is used in making toys, combs, water bottles, straws etc.
  • Polythene, polyesters, and PVC are some examples for thermoplastics.
Thermosets:

Thermosetting plastics
  • These are also called as thermosetting plastics.
  • Thermosets are plastics that cannot be recycled.
  • Thermosets cannot be moulded and reshaped.
  • They are not flexible and break if force is applied.
  • These are inexpensive and do not softens when heated.
  • These are hard and poor conductors of heat and electricity.
  • It is used as insulators in handles of cooking utensils, electrical switches etc.
  • Bakelite, silicone, and melamine are some of examples for thermosets.
