摘要:
A non-wicking underlayment board and methods for forming the same. The non-wicking underlayment board includes a foam core formed of closed cell foam with reinforcement layers encapsulated within the foam core. Outer facings formed of mineral coated nonwoven fibers are positioned on opposite faces of the non-wicking underlayment panel. The non-wicking underlayment board is useful for efficient and cost effective installation of barriers and surfaces in water-resistant and waterproof environments.

摘要:
The present invention relates to an absorbent structure with a sequence of two layers comprising at least one liquid absorption layer, a subsequent liquid storage layer with super absorbent polymer SAP, preferably SAP particles and/or SAP fibers and a subsequent liquid distribution layer, wherein the layers are connected and form a sheet structure, wherein at least the liquid storage layer and the liquid distribution layer each at least have an air laid material, preferably an air laid ply comprising cellulose fibers as main constituent, an area of the air laid material in the liquid distribution layer being more narrowly pored than an area of the air laid material in the liquid storage layer, and wherein the liquid storage layer has super absorbent polymer, in particular SAP particles, extending from the liquid storage layer into the liquid distribution layer in order to generate a return suction effect for the liquid that has passed through the liquid absorbent layer and liquid storage layer into the liquid distribution layer.

The disclosure provides a composition or set of compositions and method for producing cellular, foamed, or blown fluoropolymers such as perfluoropolymers and other thermoplastics to create a lower cost communications cable, conductor separator, conductor support-separator, jacketing, tape, wire insulation and in some cases a conduit tube as individual components or combined configurations that exhibit improved electrical, flammability and optical properties. Specifically, the foamable or blown perfluoropolymer cellular insulation composition comprises; talc and the selected fluoropolymers such as perfluoropolymers. Compounded pellets including inorganic and organic fillers resulting in products in cellular or foamable form with and without solid skin surfaces has also been realized by providing melt combinations within the pellets primarily comprising talc and a perfluoropolymer, and additives as needed to provide desired property differentiation.
摘要:
A label system including a heat shrinkable foam layer and a heat shrinkable overlaminate layer is described. The label can be applied to a container prior to and/or during heat shrinking. The shrinkage characteristics of the foam layer and the overlaminate layer are matched to one another. Also described are various methods of labeling and/or packaging using the noted label systems.
摘要:
A bio-based wetsuit and material is described where ethanol derived from sugar cane is dehydrated into ethylene and polymerized to produce bio-based ethylene propylene diene monomer (EPDM). The bio-based EPDM is mixed with additives and a blowing agent to produce sugar cane derived closed-cell foam for use in wetsuits. Depending on the wetsuit application, the density of the sugar cane derived foam may vary. In many wetsuit applications low densities such as less than 0.25 grams/cubic centimeters are desirable.
摘要:
Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, activated carbon, and water are provided. The activated carbon acts as both a water absorbent and carrier for the water. The activated carbon is able to control and increase cell size even in the presence of carbon dioxide, HFCs, and/or infrared attenuating agents. Additionally, the activated carbon permits a desired amount of water to be introduced into the polymer melt. By controlling the amount of activated carbon and its water content during an extrusion process, a broad range of cell sizes can be obtained in the extruded product. In exemplary embodiments, the activated carbon is added to a primacy extruder and water is directly injected into a secondary extruder. Alternatively, the activated carbon is compounded with a polymer resin, pre-hydrated by conditioning or steam impregnation, and added to a primary or secondary extruder.

A package is formed a closed bag made of a multilayer film and contents enclosed in the bag. The film is folded to form the bag and has flat film sides and outer edges that are reinforced by weld seams. The film of the bag has a density of 0.5 g/cm3 to 0.9 g/cm3, a printable outer layer forming an outside surface of the package, an inner seal layer made of a sealable polymer forming an inside surface of the package, and a foamed polymer core layer between the outer layer and the inner layer. The contents are a lumpy or granular bulk material.
