Thermoset polymers have a higher temperature resistance, both hot and cold – they strengthen when heated and do not warp in extremely cold temperatures, but cannot be remolded. Thermosets are essentially polymers possessing the ability to crosslink their inter-and intramolecular chains to form a solid polymer network (Dodiuk, 2013). PVC – Flexible. Thermosetting depend on “condensation polymerization process”. Monomers and oligomers can be self-polymerized or polymerized with a co-reactant or curing agent. Elastomer (Elastic polymer) Low elastic. Before you make any decision about thermosets, it is vital that you know its two sides. Flooring. The thermosetting polymers solidify throughout the molding process and cannot be softened again with heat. The presence of crosslinks hardens the overall structure. Examples of thermosets include epoxy, polyurethane, and phenolic resins. These are very hard materials with none of the high extensibility associated with typical elastomers. Examples of these materials are steering wheels, gaskets, car bumpers, windshields, door panels, and any other automotive and electrical parts. The biggest disadvantage of thermosets is that they can’t be reheated for reprocessing. The automotive, lighting, appliance, and energy industries also choose this polymer. For example, epoxies are highly elastic, tough and resistant to many chemicals while phenolic is highly flame resistant. Thermosets, on the other hand, deteriorate without showing fluid properties above certain temperatures, and cannot be reshaped with heat due to their cross-linking. Thermosetting polymer, often known as a thermoset or thermosetting plastic, is a polymer made up of highly branched molecules or a cross-linked structure. For example, a typical recyclable polyurethane thermosets can be produced by mixing (polyethylene glycol)diol (PEG), glycerol (GLY) and hexamethylene diisocyanate (HDI) with DBTDL together (Fig. 1 compares some of the properties and features of natural and synthetic polymers.
