Thermosetting and thermosoftening polymers
Did you know?
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… Webb28 feb. 2024 · Materials composed of thermoset resins have special characteristics, such as high heat, chemical, and electric resistance.

Thermoplastics can melt under heat after curing while thermoset plastics retain their form and stay solid under heat once cured. Do thermoplastics melt?
WebbThermosoftening and thermosetting Thermosoftening plastics are plastics which soften upon heating. This is due to the fact that the polymer chains are held together by weak intermolecular forces only.LDPE is a low density polyethene and this has a lowerdensity and lower melting point as it has branched chains which prevent polymer chains getting … WebbSome other thermo-softening polymers include polystyrene and polytetrafluoroethylene. Thermosetting polymers, on the other hand, do not soften when heated. Unlike thermo …
