1. A germ-repellent plastic for use in a gas pathway component of a respiratory device comprising:
A) a masterbatch, comprising:
A1) an anti-biofouling compound selected from the group consisting of a polyol, a polyether polyol, and a combination thereof; or wherein 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 wherein 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; and
(A2) an intermediate plastic comprising a random terpolymer; the random terpolymer is a random terpolymer comprising a monomer selected from the group consisting of an ethylene monomer, an acrylic ester monomer, a maleic anhydride monomer and a combination thereof or a random terpolymer comprising an ethylene monomer, an acrylic ester monomer, and a maleic anhydride monomer; or a random terpolymer comprising a polymer backbone comprising ethylene monomers, acrylic ester monomers, and maleic anhydride monomers; and
B) a basic plastic selected from the group consisting of 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.
