Most plastics contain other organic or inorganic compounds blended in. The amount of additives ranges from zero percentage for polymers used to wrap foods to more than 50% for certain electronic applications. The average content of additives is 20% by weight of the polymer.
Since many organic polymers are too rigid for particular applications, they are blended with plasticizers, oily compounds that confer improved rheology. Stabilizing additives include fire retardants to lower the flammability of the material. Colorants are common additives, although
their weight contribution is small. Fillers improve performance or reduce production costs. Many
plastics contain fillers, relatively inert and inexpensive materials that make the product cheaper by
weight. Typically fillers are mineral in origin. Some fillers are more chemically active and are called reinforcing agents.
