Hope this article is helpful to you. I think you had understood about the properties of polymers, thermoplastics, and thermosetting plastics in a detailed way. WebPMCs are of two broad types, thermosets and thermoplastics. Thermosets are solidified by irreversible chemical reactions, in which the molecules in the polymer “cross-link,” or form connected chains. The most common thermosetting matrix materials for high-performance composites used in the aerospace industry are the epoxies. Thermoplastics, on the other …

WebIn such cases, the popular choice of plastics is thermosets. Properties. Thermosets are quite unique and they differ significantly from thermoplastics. After the initial heat treatment, thermoset polymers do not get affected by additional heat exposure thus, thermoset polymers exhibit incredible resistance to heat, corrosion, and mechanical creep.
