A foam assembly system is provided. The system is configured to heat a surface of foam. After the heating of the foam, an adhesive is applied, typically a high solids adhesive. The foam is then bonded to another foam surface. It has been found that the pre-heating of the foam before adhesive application greatly enhances the bond strength between the foam and the second foam surface to which it is adhered.

A method for producing a planar composite component having a core layer (B), which is arranged between and integrally bonded to two cover layers (A, A′), wherein the cover layers contain a cover-layer thermoplastic and wherein the core layer contains a core-layer thermoplastic, comprises the following steps: a) a heated stack with layer sequence A-B-A′ is provided; b) the heated stack (A-B-A′) is pressed; c) the pressed stack is cooled, whereby the planar composite component with consolidated layers integrally bonded to each other is formed.

To improve the production method including the producibility of planar 3D components, it is proposed, that at least one of the cover layers (A, A′) in unconsolidated form comprises a fibrous nonwoven layer of 10 to 100 wt.-% thermoplastic fibers of the cover-layer thermo-plastic and 0 to 90 wt-% of reinforcing fibers having an areal weight of 300 to 3′000 g/m.sup.2; the core layer (B) in unconsolidated form comprises at least one randomly-oriented-fiber nonwoven layer (D) formed from reinforcing fibers and thermoplastic fibers of the core-layer thermoplastic, and that after the pressing the consolidated core layer(s) has/have an air pore content of <5 vol.-% and the consolidated core layer has an air pore content of 20 to 80 vol-%.

A sponge assembly with convenience features. The sponge assembly comprises at least a sponge body. The sponge body comprises a top side, a bottom side, two sides, and two ends. The sponge body further comprises a body height, a body thickness, a body length and a body width. The two sides comprise a first side and a second side. The two ends comprise a first end and a second end. The sponge assembly further comprises a logo in the top side of the sponge body. The logo comprises an embossed logo comprises an embossed height. The embossed height comprises a distance between a top surface of the top side of the sponge body and a logo surface.

Aqueous polyurethane dispersions and coatings and heat-activatable adhesives made from the dispersions are disclosed. The dispersions include a polyurethane reaction product of a polyester polyol and a polyisocyanate. The polyester polyol comprises recurring units of at least one C.sub.2-C.sub.6 aliphatic diol, at least one aliphatic or cycloaliphatic C.sub.4-C.sub.10 dicarboxylic acid, and an aromatic diacid source, which can be recycled PET. The dispersion is formulated using 1 to 3 moles of an acid-functional diol per mole of polyester polyol. Dispersions for the adhesives are produced at NCO/OH molar ratios within the range of 0.90 to 0.98. The adhesives successfully bond a wide range of plastic and metal materials, often demonstrating substrate failure, even with steel. This contrasts with commercial adhesives such as EVA that exhibit only adhesive failure with the same substrates.

A wood-grained polymer substrate includes a plurality of layers of different colors. The substrate is formed into elongated boards and used in the production of various end products similar to natural wood.

This present invention provides dissolvable solid articles comprising multiple layers of flexible, dissolvable, porous sheets, in which a coating composition is present on at least one internal surface of at least one sheet in said solid articles. The present invention also provides a process for making such solid articles.

There is provided a soft tissue implant pocket which reduces the incidence of capsular contracture. The pocket is manufactured from a biodegradable, biocompatible polyurethane foam. The polyurethane contains biodegradable polyols and the foam has a pore size configured for cellular infiltration. The soft tissue implant pocket find use in, for example, breast augmentation and reconstruction.

A composite foam article is disclosed herein. The composite foam article comprises a surface layer and abase layer with an interface therebetween. The surface layer comprises a high-resiliency polyurethane foam having an impact resilience of greater than about 50% when tested in accordance with ASTM D3574-17, and presents a seating surface. The base layer comprises a viscoelastic polyurethane foam having an impact resilience of less than about 50% when tested in accordance with ASTM D3574-17, and presents a mounting surface opposite the seating surface. The surface layer and the base layer are present in a thickness ratio of from about 17:3 to about 2:3.

Insert container for a shipment carrier, which insert container comprises at least one side wall and a bottom, which enclose a receiving space which can be closed with a lid, the at least one side wall and/or the bottom having a multilayer wall structure comprising at least one layer of at least one vacuum insulation panel and at least one layer of a particle foam, such as in particular expanded polypropylene (EPP), and wherein the at least one layer of particle foam is formed at each point with a thickness in the range from 2 mm to 12 mm.

A multilayer film can comprise: a plurality of layers, preferably 4 layers to 128 layers, comprising: a polymer A layer comprising a polycarbonate copolymer and a polymer B layer comprising a semi-crystalline polyester; wherein a differential solubility parameter (.sub.AB) of polymer A towards polymer B (.sub.AB) is greater than or equal to 2.6 MPa.sup.1/2; and an interdiffusion region between each polymer A and polymer B. The multilayer film has a dynamic flexure of greater than or equal to 200,000 cycles, as determine by bending 180 on a 10 mm radius cylinder at a rate of 1 hertz. The multilayer film has a total thickness of 40 m to 70 m, a transmission at 360 nm to 750 nm of greater than or equal to 89% and a haze of less than or equal to 1%.
