GYPSUM WALLBOARD COMPRISING LAMINATED MULTI-PLY PAPER COVER SHEETS BONDED WITH A NON-IONIC POLYMERIC BINDER AND METHODS
Provided are wallboard panels comprising laminated multi-ply paper cover sheets bonded with a non-ionic polymeric binder and a cross-linker, and methods for making the wallboard panels.
MICROLAYER MEMBRANES, IMPROVED BATTERY SEPARATORS, AND RELATED METHODS
Described herein is a multilayer microporous film or membrane that may exhibit improved properties, including improved dielectric break down and strength, compared to prior monolayer or tri-layer microporous membranes of the same thickness. The preferred multilayer microporous membrane comprises microlayers and one or more lamination barriers. Also disclosed is a battery separator or battery comprising one or more of the multilayer microporous films or membranes. The inventive battery and battery separator is preferably safer and more robust than batteries and battery separators using prior monolayer and tri-layer microporous membranes. Also, described herein is a method for making the multilayer microporous separators, membranes or films described herein.
NANOCOMPOSITE BARRIER PAPER LAMINATE
A paper laminate comprising a water-dispersible nanocomposite barrier against any permeation.
Anti-microbial, partition divider assembly for a cart such as a golf cart
An anti-microbial partition divider assembly for a cart such as a golf cart is provided. The cart has a passenger seating area, including at least one seat, a roof and a floor. The assembly includes a flexible or beam-rigid partition divider having a substrate layer made of a material which prevents airborne liquid droplets from traveling therethrough.
Cementitious panels with swellable materials and methods of providing a moisture or water barrier in cementitious panels using swellable materials
Provided are cementitious panel that include a swellable material within a core layer, a dense layer, and/or a sheet of facing material that make up a cementitious panel, as well as methods of manufacturing such cementitious panels that include a swellable material and methods of providing a moisture or water barrier in a cementitious panel.
Textile Backsheet
Textile backsheets including a nonwoven fabric and film, such as a vapor-permeable and liquid impermeable (VPLI) film or a non-permeable film, are provided, wherein the nonwoven fabric is directly or indirectly bonded to the film. Methods of making such textile backsheets and absorbent articles including the textile backsheets are also provided.
MULTI-PLY FIBROUS STRUCTURE-CONTAINING ARTICLES
Articles, for example multi-ply fibrous structure-containing articles such as multi-ply sanitary tissue products, containing two or more fibrous structure plies, and more particularly to multi-ply articles containing two or more fibrous structure plies having a plurality of fibrous elements wherein the articles exhibit improved bulk and absorbent properties compared to known articles and methods for making same, are provided.
Bonding dissimilar polymer networks in various manufacturing processes
A polymer composite of dissimilar polymers covalently bonded at the interface is disclosed. A method for bonding dissimilar polymers includes providing a first precursor to a hydrogel polymer network comprising a first coupling agent; providing a second precursor to a second polymer network comprising a second coupling agent, wherein the hydrogel polymer network and the second polymer network are different; initiating polymerization of the first precursor to form a hydrogel polymer network, wherein the first coupling agent is incorporated into the polymer network with a negligible amount of condensation; initiating polymerization of the second precursor to form a second polymer network, wherein the second coupling agent is incorporated into the second polymer network with a negligible amount of condensation; contacting one of the first hydrogel precursor or the hydrogel polymer network with one of the second polymer precursor or second polymer networks and initiating condensation between the first and second coupling agents to form a covalent bond.
Absorbent structures with high absorbency and low basis weight
Absorbent product including a laminate of at least two plies, wherein the absorbent product has a measured Valley Volume parameter greater than 11 microns and a Pit Density of greater than 25 pockets per sq. cm.
