Thermosetting polymers. Polymer with cross-links. Thermosetting polymers have different properties to thermosoftening polymers. Once moulded, they do not soften when heated and they cannot be reshaped. Vulcanised rubber is a thermoset thermoset: Material that becomes permanently hard after heating. used to make tyres.Its polymer chains are joined together by cross-links, so they cannot slide past each other easily.

Synthetic polymers are human-made polymers. From the utility point of view, they can be classified into four main categories: thermoplastics, thermosets, elastomers, and synthetic fibers. Thermoplastics are a type of polymer that become moldable and malleable past a certain temperature, and they solidify upon cooling.
