Define the terms thermosetting and thermo plastics
Answers
A thermosetting plastic is a polymer that irreversibly becomes rigid when heated. ... Initially, the polymer is a liquid or soft solid. Heat provides energy for chemical reactions that increase the cross-linking between polymer chains, curing the plastic.
Answer:
thermosetting plastics:-
➡️A thermosetting polymer, resin, or plastic, often called a thermoset, is a polymer that is irreversibly hardened by curing from a soft solid or viscous liquid prepolymer or resin.
➡️Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst.
➡️Common examples of thermoset plastics and polymers include epoxy, silicone, polyurethane and phenolic.
thermo plastics:-
➡️Thermoplastics are defined as polymers that can be melted and recast almost indefinitely.
➡️ Some of the most common types of thermoplastic are polypropylene, polyethylene, polyvinylchloride, polystyrene, polyethylenetheraphthalate and polycarbonate.
➡️Examples of thermoplastic materials are polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyamides, polyesters, and polyurethanes.
