This product is a nano-scale copper oxide filled masterbatch, grafted onto a polypropylene masterbatch with a melt flow index of 1500 through a multi-stage polymerization method. The modified copper melt-blown antibacterial masterbatch can be used to produce melt-blown nonwoven fabric through internal addition. Compared with organic antibacterial plastics, it offers long-lasting effects and exhibits excellent inhibitory effects against various molds and viruses. The copper, with its large specific surface area and mushroom-shaped microporous structure, possesses strong adsorption and sterilization capabilities, capable of adsorbing various harmful odors such as ammonia, hydrogen sulfide, and VOCs, while also exhibiting excellent antimicrobial properties.
