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.
