Thermosetting plastics
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.
the structure of thermosetting plastics are Ø Thermoplastics have long chains which are tangled together in no formal pattern Ø They have very few cross links which means that when heated they become soft allowing them to bent, pressed and formed into different shapes. Ø They become stiff as they cool

thermo plastics
Polyester resin is a thermosetting resin, generally a copolymer
thermosetting is atype of plastic which can't be recycled
Thermoplastics are the only ones that can be recycled. Thermosets cannot be recycled.

THERMOSETTING can be heated and shaped ONCE THERMO can be heated an manipulated time and time again
A thermosetting plastic, in contrast, can be melted and shaped only once. If it is then heated a second time, it tends to crack or disintegrate. Examples of thermosetting plastics (or just thermosets) include amino, epoxy, and phenolic and unsaturated polyesters.
it is a thermo setting plastic if it is what you asked
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
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.
Thermoplastics can be repeatedly softened by heating and hardened by cooling. Thermosetting plastics, however, harden permanently after being heated once. An example of thermoplastic is polypropylene (PP - recycling number 5). An example of thermosetting plastic is polyurathane (PU).
