Answer:

Thermosetting plastics are made up from long chains of molecules that are cross-linked. They have a very rigid structure.

Once heated, thermosetting plastics can be moulded, shaped and pressed into shapes. Once set they cannot be reheated since they are permanently set.

Thermosetting Plastics

When you are studying polymers in chemistry you will generally come across a typical question like “distinguish between or write the differences between thermoplastic and thermosetting plastic.” While thermoset plastics and thermoplastics sound very similar, they are totally different compounds and have different properties as well as applications.

Basically, thermosetting and thermoplastics are two different types of polymers and they are mostly separated based on their molecular bond and reaction to heat.
