Resins are any of the chemically modified natural resins or synthetic polymers which are physically similar, including thermoplastic materials such as polyvinyl, polystyrene, and polyethylene, as well as thermosetting materials such as polyesters, epoxies, and silicones. They are used as stabilizers, pigments and other components to form plastics.
The different types of resins, their primary properties, and their applications and uses are summarized in the following table:
