THERMOSETTING PLASTIC
1. the plastic materials which can be melted and molded to a desired shape only ones are called thermosetting plastic.
2. it is used to make Electrical switches, handles of various utensils, floor tiles etc.
3. examples of thermosetting plastics are Teflon ,backlite etc.
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.
