Webb12 apr. 2024 · Thermoset plastics or thermosetting polymers are liquid resins at room temperature. These polymers harden upon heating or the addition of chemicals. Besides, thermoset plastics are typically produced with resin transfer molding (RTM) or reaction injection molding (RIM). Curing a thermosetting resin transforms it into a plastic, or elastomer (rubber) by crosslinking or chain extension through the formation of covalent bonds between individual chains of the polymer. Crosslink density varies depending on the monomer or prepolymer mix, and the mechanism of crosslinking: Acrylic resins, polyesters and vinyl esters with unsaturated sites at the ends or on the backbone a…
