Polyester resin is a thermosetting resin, generally a copolymer
What else can I help you with?
Is a helmet thermoplastic or thermosetting plastic?
A helmet is typically made from thermoplastic material, which can be reheated and reshaped. Thermosetting plastic, once molded, cannot be reheated and reshaped.
Is HIPS plastic thermosetting?
No, HIPS (High-Impact Polystyrene) is a thermoplastic, not a thermosetting plastic. Thermoplastics can be melted and reshaped multiple times, while thermosetting plastics undergo a chemical reaction during curing that makes them rigid and non-meltable.
What is the opposite to thermoplastic?
The opposite of thermoplastic is thermosetting. Unlike thermoplastics, thermosetting materials irreversibly harden when heated, forming a rigid structure that cannot be melted or reshaped.
Is Bakelite thermosetting or thermoplastic?
Bakelite is a thermosetting plastic, meaning that once it is formed and cured, it cannot be melted and reshaped like a thermoplastic. This property makes Bakelite ideal for applications requiring heat resistance and durability.
Is Teflon a thermosetting polymer?
No, Teflon is not a thermosetting polymer. It is a thermoplastic polymer. Thermosetting polymers undergo a chemical reaction to form a stable, cross-linked structure when heated, while thermoplastic polymers soften when heated and harden when cooled. Teflon belongs to the latter category.

Is polyester resin a thermo plastic or thermosetting?
Once polyester resin cures (hardens) through a chemical reaction—usually with a catalyst like MEKP—it forms a rigid, cross-linked structure that cannot be melted or reshaped again. This irreversible curing process is the key characteristic of thermosetting materials. In contrast, thermoplastics soften when heated and can be remolded multiple times, which polyester resin cannot do after curing. That’s why polyester resin is widely used in fiberglass, boat hulls, automotive parts, and construction—applications where heat resistance and structural strength are essential.
