This application relates to elastomeric articles such as gloves, compositions for producing the articles and methods for their manufacture. The elastomeric articles contain particles for detectability of the articles (or portions thereof) by metal detectors and/or x-ray detectors. The articles may contain magnetic particles, highly conductive particles, or high atomic mass element-containing particles, and a viscosity modifier to ensure dispersion of the particles throughout the film layer in which the particles are present. The particles may be magnetic particles specifically, and may be coated by a corrosion inhibitor coating.
