  • Publication number: 20090264844
    Abstract: An absorbent article of the present invention may comprise a topsheet, an outer cover, and an absorbent core disposed therebetween. The outer cover may comprise an extrusion bonded laminate. The EBL may comprise a multi-layer coextruded elastomeric film and a nonwoven. The film may comprise a core layer, a first outer layer, and a second outer layer, wherein the core layer is between the first and second outer layers. The nonwoven may comprise fibers and/or filaments. The first outer layer may be non-adhesively joined to the nonwoven via extrusion coating. Further, the outer cover may be elastic to at least about 50% engineering strain. The nonwoven may have high chemical affinity for the first outer layer. The first outer layer may have a low chemical affinity for the core layer; and the multi-layer coextruded elastomeric film may have a basis weight no greater than about 40 gsm.

  • Publication number: 20080207071
    Abstract: An elastomeric laminate that does not require mechanical activation comprises an elastomeric polymer film layer bonded to one or more other substrate layers. The elastomeric film composition, physical properties of the substrate, and bonding conditions are selected and controlled to form an elastomeric laminate that is stretchable and recoverable without the use of excess material or post-lamination mechanical activation. The resulting elastomeric laminate may be manufactured on relatively simple high-speed equipment at lower cost and with improved physical properties.

  • Publication number: 20080166533
    Abstract: Moisture-resistant materials comprise an open net-like fabric with strands of varying thicknesses and polymer film thereon. The material is both resistant to water penetration and also slip resistant under dry or wet conditions. The moisture-resistant materials are suitable for use in various applications including roofing underpayment, flashing, housewrap and other construction sheet-like materials. An optional second layer of fabric may be applied to the moisture-resistant material, for example, to improve the strength, tear resistance, and scuff resistance of the moisture-resistant material.

  • Publication number: 20070178784
    Abstract: Breathable materials comprise a fabric layer and a polymer film layer thereon, the polymer film layer comprising a polymer composition and a filler, wherein the breathable material has undergone a physical manipulation to render the polymer film layer microporous such that the WVTR of the breathable material is greater than about 50 g/m2ยท24 hr, and wherein the breathable material has a first length dimension and a first width dimension before said physical manipulation and a second length dimension and a second width dimension after said physical manipulation, wherein the second length dimension is no more than about 2% greater than the first length dimension and the second width dimension is no more than about 2% greater than the first width dimension.

  • Patent number: 6071580
    Abstract: Disclosed is an absorbent, extruded, open cell thermoplastic foam. The foam has an open cell content of about 50 percent or more and an average cell size of up to about 1.5 millimeters. The foam is capable of absorbing a liquid at about 50 percent or more of its theoretical volume capacity when absorbing a liquid. The foam preferably has an average equivalent pore size of about 5 micrometers or more. The foam preferably has a structure substantially of cell walls and cell struts. Further disclosed is a method for absorbing a liquid employing the foam by elongation of the extrudate of the extrusion die. Further disclosed is a method of enhancing absorbency of an open cell foam by applying a surfactant to an exposed surface of the foam such that it remains at the surface and does not infiltrate a substantial distance into the foam. Further disclosed is a meat tray and a diaper containing the foam.

  • Patent number: 5218007
    Abstract: The present invention is directed to foams produced from poly(aryl ethers) and mixtures of poly(aryl ethers) with various non-poly(aryl ether) polymers. These foams are produced using aqueous blowing agents comprising water as the only blowing agent, or mixtures of water with another blowing agent material.

  • Patent number: 5215691
    Abstract: A method for preparing composite foam articles by the coextrusion of at least two interdigitated layers in abutting relationship to each other, wherein at least one layer of composite article comprises at least one expanded thermoplastic resinous material. At least one physical expansion agent is incorporated into at least one of the layers under a pressure sufficient to keep the expansion agent quiescent and the individual melt streams are combined and interdigitated into a composite layered stream. The composite layered stream is expressed while the operating pressures and temperatures of individual melt streams are controlled to provide a coextrusion product having a stable foam structure.
