WebbThe processing of thermosetting polymers involves three stages which are as follows. Stage 1 - The first stage of the thermosetting process is referred to as resole. This is a stage where resins exist in a fusible and insoluble condition. Stage 2 - The second stage of the thermosetting process is where a thermoset becomes partially soluble. WebbA thermosetting polymer, also known as a thermoset, is polymer material that irreversibly cures.The curing may be done by: • heat (generally above 200 °C (392 °F)) • a chemical reaction (two-part epoxy, for example) • irradiation such as electron beam processing . Thermoset materials are usually liquid or malleable before curing, so they can be molded …

Thermosoftening and thermosetting plastics - WUR

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… Webb26 juli 2024 · Thermoforming polymers can be heated and formed repeatedly.
