Webiii) Thermosetting: Thermosetting plastics are polymers which are semi-fluid in nature with low molecular masses. When heated, they start cross-linking between polymer chains, hence becoming hard and infusible. They form a three-dimensional structure on the application of heat. This reaction is irreversible in nature. The most common example of a Webthermosetting: [adjective] capable of becoming permanently rigid when heated or cured — compare thermoplastic.
