Scrubs and cleanroom pants prevent contamination in cleanrooms and medical environments. Cleanroom pants are lightweight, breathable pants that resist the buildup of ESD (electrostatic discharge) and allow workers to handle sensitive electronics. They typically are made of vinyl, Tyvek or polypropylene. Tyvek provides excellent protection against particulates, while vinyl resists oil, water and chemicals. Polypropylene protects against particulates and shedding. Scrubs are used in the medical industry to prevent the spread of contaminants. They are typically made of a cotton/polyester blend that breathes well and launders easily.
