A biocide-free, germ-repellent, crosslinked thermoset elastomer is provided. The elastomer base is a thermoset elastomer base selected from natural rubber, synthetic rubber, solid or liquid silicone rubber, or mixtures thereof. At least one germ-repelling modifier is selected from one or more of polyethylene glycol, a polyethylene glycol derivative, alcohol ethoxylate, a polymer including an isocyanate group, a polymer including an allyloxy group, siloxane, polyether modified silicone, polysorbates and copolymers or mixtures thereof. The germ-repelling modifier is permanently bonded to the thermoset elastomer base through a chemical reaction during extrusion, molding, or curing. This chemical reaction also crosslinks the thermoset elastomer base.

A thermoplastic elastomer composition contains component (A-2), component (B), and component (C). The content of component (A-2) is 5 parts by weight or more and 95 parts by weight or less with respect to 100 parts by weight of the total amounts of components (A-2) and (B), and the content of component (C) is 0.005% by weight or more and 3% by weight or less with respect to 100% by weight of the whole amount of the thermoplastic elastomer composition. Component (A-2) is a crosslinked product of component (A-1), which is an ethylene copolymer containing a monomer unit derived from propylene and/or α-olefins having 4 to 10 carbon atoms, and a monomer unit derived from ethylene, and having a Mooney viscosity (ML.sub.1+4, 125° C.) of 50 or more. Component (B) is a propylene polymer and component (C) is an antifungal agent.
