Solution
Thermoplastics :
A thermoplastic is a plastic material that softens when melted and gets solidified when undergoes cooling.
These types of plastics can be reshaped or remolded numerous times.
Thermoplastic substances can be recycled or reused.
Examples are: Polyester, Polypropylene, Polystyrene, Teflon, Acrylic, etc.
Thermosetting plastics:
Thermosetting plastics are a type of plastic that exists in its permanent solid state after being molded once and doesn't undergo melting even when exposed to extreme temperatures.
These types of plastics cant be reshaped and therefore are not reusable.
Examples are: PVC (polyvinyl chloride), Polystyrene, Polyethylene, Polypropylene, etc.
