Abstract
The present invention relates to a foamable composition comprising a low viscosity thermoplastic composition comprising at least one ethylene/.alpha.-olefin. The foamable composition may comprise a single ethylene/.alpha.-olefin or a blend of such. Optionally, the foamable composition may further comprise at least one diluent including waxes, plasticizers such as oil, tackifying resin, and mixtures thereof. The present invention also relates to a method of foaming such compositions and articles constructed therefrom. More specifically, the present invention relates to foamable thermoplastic compositions having particular utility as cabinet sealant and as foam layers in disposable articles such as disposable diapers, incontinent devices, medical devices such as bandages and dressings, as well as a variety of other uses.
