Answer 1

Thermoplastics are defined as polymers that can be melted and recast almost indefinitely. They are molten when heated and harden upon cooling. When frozen, however, a thermoplastic becomes glass-like and subject to fracture.

Examples of thermoplastic materials are polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyamides, polyesters, and polyurethanes.

$\huge\underline\bold\red{ Thermosetting - }$

Thermosetting plastics, such as phenol-formaldehyde, cannot be remouldedCompare thermoplastic.

Examples of thermosetting plastics include bakelite, urea-formaldehyde resins.

Answer 2

thermoplastic - denoting substances (especially synthetic resins) that become plastic on heating and harden on cooling, and are able to repeat these processes.

example - polypropylene, polyethylene

thermosetting - A thermosetting polymer, resin, or plastic, often called a thermoset, is a polymer that is irreversibly hardened by curing from a soft solid or viscous liquid prepolymer or resin. Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst.

example - epoxy, silicone
