Thermosetting polymer

Thermosetting polymers, or thermosets, are a type of polymer that becomes irreversibly hard when heated and cured. Unlike thermoplastics, which can be melted and re-shaped multiple times, thermosetting polymers undergo a chemical change during the curing process that results in a rigid, inflexible material. This curing process typically involves a reaction with a hardener or cross-linking agent, which links the polymer chains together, creating a three-dimensional network.
