Properties of thermosetting plastic
WebThermosetting polymer, often known as a thermoset or thermosetting plastic, is a polymer made up of highly branched molecules or a cross-linked structure. The thermosetting polymers harden throughout the moulding process and cannot be re-softened with heat. Bakelite and urea-formaldehyde resins are examples of thermosetting polymers. WebThermoplastic Additives – They are used to increase the fracture toughness of epoxy resins. Only relatively low MW TPs can be dissolved in epoxy resins. Commonly used thermoplastics are phenoxy, polyether block amides, PVB, polysulfone, polyethersulfone, polyimide, polyetherimide, nylon.

WebThermosetting plastics contain polymers whose cross-linking takes place together at the time of curing process. This certainly results in the formation of an irreversible chemical bond. Furthermore, the process of cross-linking eliminates the risk of the product remelting on the application of heat.
