Solution
The correct option is D Bakelite
Thermoset materials are usually liquid or malleable prior to curing and designed to be moulded into their final form or used as adhesives. Others are solids like that of the moulding compound used in semiconductors and integrated circuits (IC). Once hardened a thermoset resin cannot be reheated and melted to be shaped differently.
Thermosetting resin may be contrasted with thermoplastic polymers which are commonly produced in pellets and shaped into their final product form by melting and pressing or injection molding. Bakelite, a phenol-formaldehyde resin used in electrical insulators and plastic ware.
