Thermoset vs Thermoplastic: Definition, Processes, and Differences

In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (resin). Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst. Heat is not necessarily applied externally, but is often generated by the reaction of the resin with a curi… Webb16 mars 2024 · Thermoplastics can be molded and remolded in the presence of heat without losing structural integrity, while thermosets can be molded only once. Of the two, thermoplastics are better suited for all-purpose products that need to be strong and flexible, while thermosets make better high-performance products. city of newport minnesota
