Polyester resin is a thermosetting resin, generally a copolymer
it is a thermo setting plastic if it is what you asked
The three I can think of are polyester resin ,urea formaldehyde and polyurethane
Polyester resin is a thermosetting resin, generally a copolymer
Reinforced Thermosetting Resin Plastic (RTRP) Pipe.
Thermosetting plastics such as polyoxybenzylmethylenglycolanhydride better know as 'Bakelite' and some others.
Thermosetting plastics. Once cooled and hardened, these plastics retain their shapes and cannot return to their original form. Thermosetting plastics dont melt (i think) :)
Fibreglass resin is a polyester.
Yes, Formica is a type of thermosetting plastic. Thermosetting plastics are materials that undergo a chemical reaction to form a rigid structure that cannot be softened or reshaped by heat once it has cured. Formica is commonly used as a laminate material for countertops and other surfaces.
If it is plastic (many speedboats are metal) it will be the plastic Epoxy Resin (exactly the same as the glue) with fiberglass cloth to reinforce it. Epoxy Resin is very strong but somewhat brittle (like concrete), the fiberglass prevent cracks in the Epoxy Resin from growing and reinforces it (like the steel rebar in reinforced concrete does).
No, epoxy is not a thermoplastic. Epoxy is a thermosetting polymer, which means it undergoes a chemical reaction to harden irreversibly when exposed to heat or a curing agent. This makes it different from thermoplastics, which can be melted and reshaped multiple times.
Answerthermoplastics 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.
