defiend thermoplastic and therosets plastic with example
Answers
Explanation:
A thermoplastic is a material, usually a plastic polymer, which becomes more soft when heated and hard when cooled. Thermoplastic materials can be cooled and heated several times without any change in their chemistry or mechanical properties. When thermoplastics are heated, they melt to a liquid. Ex ➡ polypropylene, polystyrene, cellulose acetate, PTFE (Teflon), nylon, polyketone, etc.
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. Ex ➡ Epoxy resin, melamine formaldehyde, polyester resin and urea formaldehyde.
Explanation:
Thermoplastic:
A thermoplastic, or thermosoftening plastic, is a plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling.
Polyethylene, polypropylene, polyvinyl chloride, polystyrene, polybenzimidazole, acrylic, nylon are examples of thermoplastics.
Thermosetting plastic
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.
The main thermosetting plastics are epoxy resin, melamine formaldehyde, polyester resin and urea formaldehyde.
