Functional additives are specialized chemical products that provide a variety of effects that many other industries rely on. Polymer additives are materials used based on their properties or functions. They can be unique molecules or a mixture of molecules called a formula. The physical and chemical properties of individual molecules or formulated mixtures of molecules, as well as the composition of the mixture, influence the properties of the final product. Other industrial sectors such as automotive, aerospace, food, cosmetics, agriculture, manufacturing and textiles are highly dependent on functional additives.
