What plastics are thermosetting plastics?

Answer 1

Thermosetting plastics are a type of plastic made of long, cross-linked molecule chains. Their structures are very rigid. Thermosetting plastics can be moulded and shaped when heated, yet they cannot be heated again after they set.

Answer 2

Thermosetting plastics are simply plastics when moulded into shape and allowed to cool will not change shape when heated again they will char or burn an example of a thermosetting plastic is urea formaldehyde.

Answer 3

A thermoset plastic is a nonmeltable plastic that was made by melting down a powder and when that happens, all the little plastic molecules theoretically combine to make one giant molecule. This is why you cant remlt it, all that would happen if you tried to melt the thermoset plastic, is the plastic would burn away. Think of it like this: think of roaps, and that each rope is a molecule, when you tie the ropes together you can pull them apart, think of that al melting normal plastic together, in that it still has a melting point where the molecules come apart. Now if you were to weave each strand together that makes up the rope, you wouldn't be able to pull it apart. Teoretically that's what happens in thermoset plastic, all the molecule come together and form a giant one. So that means we can think of the hood of a big rig to be one giant molecule.

Answer 4

As a broad answer, thermosetting plastics are the ones that cannot be recycled due to degradation of the cross linking bonds within the atomic structure; it simply does not break back down to its original monomer components. These are usually very stiff and strong plastics, such as plexie glass.

Answer 5

Phenolic, epoxy, amino and unsaturated polyesters are thermosetting plastics. Due to their property of becoming set solids while processing due to chemical changes, they are named as thermoset plastics.
