thermosetting resin

Thermosetting resin is a type of plastic material that hardens permanently when heated or cured through a chemical reaction. Unlike other plastics that can be remelted and reshaped, once set, thermosetting resins do not soften again. They form a strong, durable, and heat-resistant network structure, making them ideal for items like electrical insulators, automotive parts, and cookware. Examples include epoxy and phenolic resins. Their stability and high performance under stress make thermosetting resins valuable in manufacturing components that require toughness and heat resistance.
