CONCENTRATE COMPOSITION FOR POLYMERS

摘要

The invention is directed to a concentrate composition suitable for melt blending of nano particle size additives into polymers or polymer blends, said composition comprising a waxy matrix carrier material having an melting point of at least 40° C., in an amount of 10 to 99.9 wt. %, based on the weight of the composition and metal or metaloxide primary nanoparticles having a particle size substantially between 1 and 500 nm, wherein the metal oxide nano particles are zinc oxide or silver oxide.
