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.

The basic binding materials in plastic are resins, which undergoes polymerization and condensation reactions during the preparation of plastic. There are two types of plastics, thermoplastics and thermoset plastics. Examples of thermoplastics include polythene (PE), polypropylene (PP), polyvinyl chloride (PVC), polytyrene (PS), nylons, and polytetrofluoro ethylene (PTFE or Teflon). Examples of thermoset plastics include phenolic resins, amino resins, polyester resins, silicon resins, epoxy resins, and polyurethanes. This handbook discusses the types, properties, uses, and advantages of thermoset plastics.
