Quick Summary

An extender is a substance added to a product to increase its bulk, acting as a diluent, adulterant, or modifier. In the chemical industry, extenders are also referred to as additives. These are incorporated into materials, such as plastics, to achieve specific properties or reduce costs. For instance, in surface coatings, specialty additives, including rheological-control additives like thickeners, are used in small percentages to significantly impact performance and application. These additives can alter viscosity, aid in film formation, and improve durability.1234
