Title
(EN) ARC FLASH PROTECTIVE MATERIALS
(FR) MATÉRIAUX DE PROTECTION CONTRE LE FLASH D'ARC
Abstract
(EN)
Relatively lightweight laminate structures having an outer textile layer, a heat reactive material, a middle layer, a flame retardant adhesive material and an inner layer, wherein the flame retardant adhesive material is positioned in a pattern so as to form a plurality of pockets, each of the pockets defined by (a) the middle layer, (b) the inner layer, and (c) a portion of the flame retardant adhesive material. The laminate structures can provide protection from an exposure to an electrical arc.
(FR)
L'invention concerne des structures stratifiées relativement légères comprenant une couche textile extérieure, un matériau réactif à la chaleur, une couche intermédiaire, un matériau adhésif ignifuge et une couche intérieure, le matériau adhésif ignifuge étant positionné selon un motif de manière à former une pluralité de poches, chacune des poches étant définie par (a) la couche intermédiaire, (b) la couche intérieure, et (c) une partie du matériau adhésif ignifuge. Les structures stratifiées peuvent fournir une protection contre une exposition à un arc électrique.
