Nitrile, commonly used in the production of disposable gloves, also known as NBR (Nitrile Butadiene Rubber) is a material of synthetic origin derived from the polymerization of Butadiene and Acrylonitrile. It has been defined as synthetic rubber, as the raw material is produced in the liquid state (such as Latex and unlike the PVC-Vinyl) and for its ability to emulate rubber’s elasticity.
Nitrile gloves were conceived as an alternative to Latex gloves for use in allergic subjects and to reduce the sensitization to Latex proteins, but the current large development is also due to their characteristics of chemical and mechanical resistance, which makes them suitable also in conditions where Latex gloves and Vinyl gloves are not. In addition, unlike Latex and Vinyl, Nitrile is suitable for contact with oily and fatty food, in line with current legislation on items and articles intended for contact with food (Dir 2004/195/EEC – CE Reg. 10/2011).
