WebSolution. A thermoplastic polymer can be repeatedly softened on heating and hardened on cooling. Hence, it can be used again and again. The examples are polythene, polypropylene, etc. A thermosetting polymer is a permanent setting polymer as it gets hardened and sets during moulding process and cannot be softened again. WebThermosets are a class of important polymers having three-dimensional cross-linked network structures. Typical thermosets such as epoxy resin, phenolic resin, and unsaturated polyester resin have been widely used as electronic encapsulating materials, coatings, adhesives, and matrix of composites [1–5].
