Nucleation efficiency of talc in the foaming behaviour and cellular structure of polymer based foams

There are disclosed polymer-based foam compositions comprising a polymer; and up to 20 wt. % talc particles, based on the total weight of the composition. The talc particles are microcrystalline talc. The polymer is selected from a thermoplastic, a thermoplastic elastomer, and a rubber. There are fu...

Beschreibung
Zusammenfassung:	There are disclosed polymer-based foam compositions comprising a polymer; and up to 20 wt. % talc particles, based on the total weight of the composition. The talc particles are microcrystalline talc. The polymer is selected from a thermoplastic, a thermoplastic elastomer, and a rubber. There are further disclosed uses of the said polymer-based foam compositions, products comprising the said polymer-based foam compositions, and methods of formation of the said polymer-based foam compositions.
