Thermoplastics are easily molded because they soften when heated and harden when cooled, allowing them to be reshaped multiple times. This characteristic is a result of their long, linear molecular chains, which can move and slide past each other when exposed to heat, making them highly moldable.
Thermoplastics are lightweight, flexible, and have good impact resistance. They can be easily molded and reshaped when exposed to heat, making them versatile for various applications. Additionally, thermoplastics are recyclable and environmentally friendly.
Thermoplastics plastics can be heated and then moulded into a shape or form, but thermosetting cannot. Each plastic can be moulded into a 'shape or form', it is just that thermoplastics, once they have been moulded, they can be re-heated and moulded again, where-as once thermosetting plastics have been moulded, if re-heated and you try to remould it, it will just make it brittle and snap instead.

It gets melted and then moulded into another object
Yes. Thermoplastics are "heat-softening". Provided that you don't heat them to the point of destruction, thermoplastics can be remoulded and reused easily.
Thermoplastics can be resoftened and remoulded several times,thermosetting can be heated and moulded only once into an irriversible shape.=)

it means that plastic can easily change shape. You can easily change the shape of a plastic object.

Its viscosity (it becomes pliable when warmed by the hand).
Thermoplastics become less viscous or melt when heated. such plastics may be recycled that means may be moulded into another shape on melting. Thermoset plastics do not - for instance melamine.
There are two types of plastics: thermoplastics and thermosetting polymers. Thermoplastics are the plastics that don't undergo chemical change in their composition when heated and can be moulded again and again; examples are polyethylene, polystyrene, polyvinyl chloride and polytetrafluoroethylene (PTFE).[3] Thermosets can melt and take shape once; after they have solidified, they stay solid.
There are a few differences between the two. Thermoplastics usually contain additives to change the properties of the material such as polypropylene. Thermosets usually contain catalysts that change the state of the material at the molecular level. The main difference between thermoplastics and thermosets is that: -Thermoplastics can be re-melted and recycled fairly easily -Thermosets typically are cured and molded into shape and are not recycled as easily

When the links between the carbon atoms in the monomers becomes 2 and 3 dimensional the chains become much stronger. These plastics are known as Thermosets. Once these plastics are set they cannot be re moulded and shaped like thermoplastics can.
