Nitrile, a copolymer containing acrylonitrile, butadiene and methacrylic acid, is structurally different and presents fewer variables to the manufacturing team. Gloves manufactured using this material provide relatively fewer particulates, lower ionic extractables, better ESD protection and stronger resistance to chemicals. Essentially, these are the performance characteristics of a glove required today in critical-environment manufacturing. HDD manufacturing is becoming increasingly sensitive to contamination. Natural rubber cleanroom gloves generally are no longer able to meet some of the specifications demanded from the end users. As a result, HDD manufacturers, including those subcontracting in components, have replaced natural rubber gloves with nitrile cleanroom gloves in a majority of their production processes.
Similarly, although microelectronic and semiconductor manufacturers largely use vinyl gloves because of their manufacturing requirements, there has been a gradual migration to nitrile gloves in recent years, driven mainly by the increasingly stringent manufacturing environment in this industry.
