Abstract:
A laminar structure comprised of at least one layer of glass and a sheet of plasticized PVB containing an adhesion control agent is provided wherein pin point pockets of air which are entrapped in said sheet coalesce and cause delamination of said structure, delayed delamination and associated defects are prevented by adding a nucleating agent with the plasticized PVB by coating the sheet or glass surface with a nucleating agent, by extruding the PVB sheet with the nucleating agent in the composition, or by forming the nucleating agent in situ during the extrusion or lamination process.
Abstract:
A laminar structure comprised of at least one layer of glass and a sheet of plasticized PVB containing an adhesion control agent is provided wherein delamination resulting from air being from air being dispersed or entrapped and dissolved in the PVB is controlled by use of a surface energy modifying agent, said surface energy modifying agent being selected to provide a total surface energy for the sheet of less than 52 dynes/cm.
Abstract:
The present invention concerns a breathable product for protective mass transportation and cold chain applications, in particular a reflective sheet for covering temperature sensitive products the reflective sheet having at least a first layer made of a highly reflective moisture vapor permeable substrate having an outer side and an inner side, wherein said inner side comprises in addition at least a metal layer deposited by a PVD process to provide a thermal insulation through high reflection low convection while providing controlled moisture vapor permeability.
Abstract:
A moisture vapor permeable metalized composite sheet is formed by coating a moisture vapor permeable sheet with at least one metal layer and at least one outer organic coating layer. The moisture vapor permeability of the composite sheet is at least about 80% of the moisture vapor permeability of the starting sheet. The composite sheet provides a barrier to air and liquid water infiltration while having high moisture vapor permeability and good thermal barrier properties. The composite sheet material is suitable for use as a building construction wrap such as roof lining and house wrap.
Abstract:
A durable metallized moisture vapor permeable sheet is formed by coating a moisture vapor permeable sheet with at least one metal coating comprising a layer of a corrosion resistant metal or a plurality of metal layers having differing compositions. The metallized moisture vapor permeable sheet material is suitable for use as a building construction wrap such as roof lining and house wrap, and as EMF radiation shielding material.
Abstract:
Wood pulp papers are provided that are useful in end uses requiring microbial barrier properties such as medical packaging, air filters, liquid filters, and other uses and the papers have significantly improved bacterial barrier properties in contrast to wood pulp papers known in the art as measured by Log Reduction Values determined by ASTM F-1608.
Abstract:
A self-adhesive laminate with an emissivity of no greater than about 0.40 made of a sheet layer having first and second outer surfaces, the sheet layer comprising at least one layer selected from the group consisting of nonwoven fabrics, woven fabrics, nonwoven fabric-film laminates, woven fabric-film laminates, films, paper-film laminates, and composites thereof with at least one multi-layer coating on said first outer surface of the sheet layer, said multi-layer coating comprising a first metal coating layer adjacent the first outer surface of the sheet layer; and an outer organic coating layer of a composition containing a material selected from the group consisting of organic polymers, organic oligomers, compounds, and combinations thereof, deposited on the metal layer; and with an adhesive layer coating the second outer surface of the sheet layer and wherein the sheet layer coated with said multilayer coating is creped.

Abstract:
The invention provides a process for directly manufacturing a diamine/dicarboxylic acid salt with a low water content. The process includes reacting a diamine with a dicarboxylic acid to form a diamine/dicarboxylic acid salt. The reaction of the diamine and the dicarboxylic acid is carried out in the presence of about 0.5% to about 25% by weight water, based on the weight of the reaction mixture, while providing conditions in the reaction mixture such that the reaction mixture is in substantially solid particulate form.
