Abstract
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.
