The layer structure comprises a porous backing material, an intermediate layer applied to one side of the porous backing material and an adhesive layer made of a silicone gel applied to the intermediate layer.

Compositions-of-matter comprising a matrix made of one or more, preferably two or more elastic layers and one or more viscoelastic layer are disclosed. The compositions-of-matter are characterized by high water-impermeability and optionally by self-recovery. Processes of preparing the compositions-of-matter and uses thereof as tissue substitutes or for repairing damaged tissues are also disclosed.

A viscoelastic plastic interlayer intended to be arranged between two glass sheets of a glazing in order to provide it with vibroacoustic damping properties, includes two outer layers of thermoplastic adhesive, an inner layer arranged between the two outer layers, the inner layer having a loss factor tan δ greater than or equal to 1.6 at 20° C. and for a frequency range of between 2 kHz and 8 kHz, and first and second barrier layers arranged respectively between the outer layers and the inner layer 3, and composed of a viscoelastic plastic material.

A floor panel includes several side edges extending in the peripheral direction of the floor panel behind one another and separated from one another by a corner, and a plastic top surface delimited by the side edges. A portion of the top surface is provided with at least two elongate zones with a mutually different texture which also deviates from the texture of an area of the top surface which adjoins the zones. The zones form edge zones, each of which extends along one of the side edges or the long sides of the zones adjoin each other.

A polymer material consists of expanded polyethylene terephthalate with a density of 30 kg/m.sup.3 to 750 kg/m.sup.3 and an intrinsic viscosity of 0.5 dl/g to 1.0 dl/g. Polyethylene terephthalate granules with an intrinsic viscosity ranging from 0.5 dl/g to 1.0 dl/g which are produced from polyethylene terephthalate waste products or virgin polyethylene terephthalate are dried to a moisture content of 50 to 7000 ppm, then loaded into a dosing hopper of an extruder where said material is mixed with dyes or processing aids. The polyethylene terephthalate is then extruded while simultaneously feeding nitrogen or carbon dioxide or isopentane or n-pentane or freon or mixtures thereof into a connector upstream of the die. In the die and at the outlet from the die, temperature- and pressure-controllable expansion of the polyethylene terephthalate melt is carried out to a density ranging from 30 kg/m.sup.3 to 750 kg/m.sup.3.

The present disclosure provides articles having conformal layers and methods of making such articles. An article includes a first polymeric layer having a substantially planar major surface and an opposing major surface bonded to a second polymeric layer. One major surface of the second polymeric layer is conformal to the first polymeric layer while the opposing major surface defines a cavity having at least one wall. The second polymeric layer also has a channel connecting the cavity to at least one edge of the second polymeric layer or to the planar surface of the first polymeric layer. A surface of the cavity exhibits an advancing contact angle with water of less than 90 degrees. A method includes obtaining a tool having protruding features; disposing a first polymer on the protruding features; disposing a second polymer on the first polymer; and applying compression to the polymeric tooling, the first polymer, and the second polymer at an elevated temperature to form the article. The articles can be formed to have small cavities for use as precision fluidic devices, such as blood glucose testing strips.

A composite material includes a porous foam, having a density of less than 1 g/cm.sup.3, with a polymer matrix including chitosan, chitin, or chitosan oligosaccharide, and a first laminate adhered to a first surface of the porous foam.

Drinking containers, more specifically to a disposable container for hot and cold beverages are disclosed. The technical result consists in the creation of a disposable cup that is simple to produce, fit for use and made of a multi-layered material based on virgin or recycled (obtained from polyethylene terephthalate waste) polyethylene terephthalate foam. The proposed disposable cup has a side wall in the form of a solid of revolution and a base that are interconnected, wherein a lip is formed in the upper portion of the side wall, and the side wall and the base are made of multiple layers and include at least one layer of polyethylene terephthalate foam with a density of 100 kg/m.sup.3 to 900 kg/m.sup.3, with a characteristic viscosity of 0.5 dl/g to 1.0 dl/g, connected by a melt with a layer of polyethylene copolymer.

A fuel container having walls defining a space in which fuel is to be contained, a layer of deformable material bonded to the external surfaces of the container walls, and a self-sealing layer of fuel-activated swellable material bonded to the deformable material, wherein said self-sealing layer is a latex foam, in particular a natural rubber latex foam, comprising a non-ionic associative thickener as rheology modifier and optionally other additives such as foam enhancers, foam stabilizers, accelerators and vulcanization components.
