Title (EN) PERMEABLE, SHAPED STRUCTURES OF ACTIVE PARTICULATE BONDED WITH PSA POLYMER MICROPARTICULATE
(FR) STRUCTURES PERMEABLES EPOUSANT LES FORMES ET CONSTITUEES DE PARTICULES ACTIVES LIEES A DES MICROPARTICULES DE POLYMERE ADHESIF AUTOCOLLANT
Abstract: front page image
(EN)A fluid permeable composite structure having active particulate bonded together using a pressure-sensitive adhesive (PSA) polymer microparticulate. Use of the PSA polymer microparticulate to bond the active particulate together produces a bonded structure that, unlike previously-developed active bonded structures, is flexible and therefore can be conformed into a variety of shapes. The shaped structures may be used as gaseous filters in a wide variety of respirators.
(FR)L'invention porte sur une structure composite perméable aux fluides, dont les particules actives sont liées ensemble à l'aide de microparticules d'un polymère adhésif autocollant. Le recours à cet adhésif pour lier les particules actives produit une structure liée qui, contrairement aux structures actives et liées antérieures est souple et peut de ce fait prendre une variété de formes et servir notamment de filtre à gaz dans différents types de respirateurs.
