A liquid rubber composition comprises a latex, a vulcanizing agent, and an antimicrobial agent selected from a halide of silver, gold, or zinc. Preferably, the antimicrobial agent comprises silver chloride and the vulcanizing agent comprises sulphur. The latex may be natural rubber, which has been optionally modified to reduce its protein content or may be a synthetic latex, such as polyisoprene. Typically, 100ml of the composition has a viscosity of no more than 15 seconds when measured using a #5 Ford Flow Cup at 16-18ºC. The composition may be vulcanized to make a solid rubber product with antimicrobial properties. The product may be in the form of a latex glove or a rubber sheet. In a further aspect, the use of zinc oxide as an antimicrobial agent in a liquid rubber or vulcanized rubber composition is disclosed.
