Thermoplastic polyolefin-based nanocomposites have found applications in the step assist for GM Astro vans and film for food and pharmaceutical packaging. Polycarbonate- and ABS-based nanocomposites can be used for flame retardant computer housing and flame retardant monitor housing. Elastomer-based nanocomposites are finding use in tennis balls. 

The nano-level dispersion of clay in thermoplastic olefin (TPO) polymer has potentially provided a platform for its use in automotive body panels of Volvo cars. The governing factors are light weight, consistent physical and mechanical properties, improved aesthetic appearance, improved wear resistance, and low temperature ductility. Recyclability of nano-clay incorporated thermoplastic olefin nanocomposites has provided an opportunity for their use in step assists and trim and panel in Hummer cars. 

The relative permeability of the elastomers decreases with increase in nano-clay incorporation by several folds. The significant decrease in oxygen permeability of isobutylene-copolymer nanocomposites replaces traditional inner-liners of tires for truck applications [113]. 

The decrease in permeability and enhanced gas barrier property of clay-polymer nanocomposites makes them viable for packaging application.
