The biocide used in Elastoguard compounds is Alphasan® silver-sodium-sirconium-phosphate (silver-NZP) ion-exchange resin. It permeates the entire rubber part to provide skin-to-core protection. The silver-based antimicrobial agent is nonleaching, so parts achieve thorough and long-term protection than is offered by organic biocides. Suitable for seals, gaskets, O-rings, wheels, casters, diaphragms, tubing, and belts.
