When thermosetting polymers are heated for the first time, chemical bonds form between the polymer molecules. They link together in a giant network. These strong bonds make the plastic set hard and it cannot be softened again by heating.
Thermoset plastics are intially heat-treated to cure them and set them in their final form. Subsequent heating doesn't do much of anything unless it's so hot they actually burn.
the plastic is able to be moulded and you can change its shape. =)=)=)
It hardens. Thermo - heat, set - setup or harden.
Thermoplastics are softened by heating.

teflon is thermoplastic as it contains a linear chain and is not crosslinked..

Polyester resin is a thermosetting resin, generally a copolymer
Some kinds of materials that set with heat.
As a polymer the properties are: Urea formaldehyde is rigid, strong, brittle and has a high surface hardness, which makes it scratch resistant. It is also heat resistant, as it is a thermosetting polymer. It has a very low water absorption rate, and it is a good electrical insulator. UF has a high tensile strength and it is opaque. this is all that i could find, and it is only for AS level resistant materials.
It is a thermosetting polymer
Thermoplastic.
Curing of a thermosetting polymer is irreversible.
Polyethylene is a thermoplastic polymer.
Polyvinyl chloride is a thermoplastic polymer.

For example thermoplastic and thermosetting polymers, natural and synthetic polymers.
Yes, polymers do conduct heat. How well this happens depends on the polymer concerned.
Thermosetting materials fuse under heat. The change is usually permanent.
