A latex article with static dissipating property

Abstract

An elastomeric article, specifically an unsupported glove with two layers where the outer layer has ESD properties and its method of manufacturing is described here. The outer layer is especially formulated with a combination of fillers to reduce the surface resistance and volume resistance and helps to dissipate static charge which builds up as a result of triboelectric action. The wearer of this glove will not get any shock due to static charge which is experienced when wearing a conventional nitrile glove specially in applications such as spray painting
