Question

Explain the different between thermoplastic and thermosetting plastic

Answer 1

Answer:

Thermoplastics

Multicolor Thermoplastic Resin

Thermoplastic commonly referred to as thermoplastic polymers are polymers that can be repeatedly heated and molded without effecting any change in their chemical or physical properties. Thermoplastics can be re-melted and re-shaped any number of times. They are usually stored in the form of pellets prior to the molding process.

Common Examples of Thermoplastics And Their Use

Teflon: Used as lubricant for sliding doors and making machining parts such as gaskets.

Polyvinyl Chloride: Used in making toys, pipes, cabinets and electrical insulators.

Polypropylene: Used to make heat proof medical equipments and laboratory equipments.

Acrylic: Used to make lightweight glass, eye lenses and battery covers.

Polyethylene: Used to make gas tank coating, bullet resistant vests and movable machine parts.

Nylon (Polymide): Used to make clothing, mechanical and automotive parts.

Thermosetting Plastics

Thermosetting PlasticsPolyester Resins

Thermosetting PlasticsPolyester ResinsThermosetting plastics also referred to as thermosets are plastics which remain in a permanent solid state after being molded and hardened, they cannot be reshaped or be recycled. Polymers within the material cross-link during the molding process to result into an unbreakable, irreversible bond. Thus, thermosets will not melt even when exposed to extremely high temperatures.

Answer 2

Hey friend,

Here is the answer you are searching for,

Thermoplastic : Plastics switch sofen on heating and can be remoulded. For eg:PVC,Nylon.

Thermosetting plastics : Plastics which do not soften on heating and cannot be remoulded. For eg:Bakelite,Melamine

HOPE IT HELPS YOU.
