Abstract
A germ-repellent plastic contains an anti-biofouling compound, and a basic plastic. The anti-biofouling compound is optionally selected from the group of a polyol, a polyether polyol, a polyol derivative, and a combination thereof; or the anti-biofouling compound is selected from the group consisting of a polyether, a poly (ethylene glycol) ether, a polysorbate, and a combination thereof; or the anti-biofouling compound is selected from the group consisting of poly (ethylene glycol) sorbitan monolaurate, poly (ethylene glycol) sorbitan monooleate, poly (ethylene glycol) sorbitol hexaoleate, ceteareth, and a combination thereof. The basic plastic is not a blend of a low-density polyethylene polymer and an ethyl vinyl acetate copolymer, a blend of a polypropylene polymer and an ethyl vinyl acetate copolymer, a blend of polyolefin elastomer polymers and a polyvinyl chloride polymer. A method for manufacturing such a germ-repellent plastic and a germ-repellent plastic item are also described.
