A composite article (30), comprising at least one fibrous layer (12), and at least one thermoplastic epoxy web layer (14) located in direct planar contact with the at least one fibrous layer (12), the at least one thermoplastic epoxy web layer (14) being adapted to substantially phase separate during a molding and/or curing process.

An ultra violet stable polyester membrane with a polyacrylic coating on one side and a coated pressure sensitive adhesive coating on its other side capable of allowing water vapor to pass through it. The pressure sensitive adhesive is formed of a copolymer comprising a backbone of n-butyl acrylate, 2-ethylhexyl acrylate, and vinyl acetate which is mixed with at least one surfactant and emulsified to produce air bubbles which form pores when the copolymer is set with about 80% to about 90% of the pore sizes ranging from about 200 microns to about 300 microns and being uniformly distributed to form a flow path through the pressure sensitive adhesive.

The present invention relates to a biodegradable container comprising a thermoformable structural layer with tear resistance and low cost, and optionally an adhesive barrier layer, an adhesive active layer and/or a layer in direct contact with the product, all of which are based on biodegradable polymers. Furthermore, the present invention relates to the method for obtaining same and to use thereof for contact, transport and/or storage of perishable products.

Described is a composite made from a woven fabric, a non-woven fabric, or a knitted face fabric and a non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric is needle punched such that fibers protrude into the non-woven fabric. The woven fabric, the non-woven fabric, or the knitted face fabric has a first polymer having a first melting point and a second polymer having a second melting point being higher than the first melting point. The nonwoven backing material comprises a third polymer having a third melting point and a fourth polymer having a fourth melting point being higher than the third melting point. The woven fabric, the non-woven fabric, or the knitted face fabric is further bonded to the nonwoven backing material applying heat to at least partially melt or soften the first polymer and the third polymer such that they bond together.

Provided is a functional fabric including a base fabric layer; and an insulation flexible sheet attached to at least one surface of the base fabric layer. The insulation flexible sheet includes a first flexible base; and an insulation coating layer attached to at least one surface of the base. The insulation flexible sheet may additionally include a second flexible base on the insulation coating layer. Accordingly, the functional fabric may have effective insulation properties by using silica particles having pores in a small amount used, and may have excellent strength due to the strength of the silica particles. In addition, Manufacturing methods of an insulation flexible sheet and a functional fabric are provided.

The present invention provides a metal pipe coated on at least a section of the metal pipe with a polyolefin coating system, wherein the system consists of the following layers: (a) optionally, a corrosion protective layer of a chromate, phosphate or other salt; (b) a polyolefin based adhesive, preferably in a thickness of 0.3-5 mm; (c) a PE or PP coating layer, preferably in a thickness of 1-10 mm; (d) optionally, an adhesion promoting layer between the polyolefin based adhesive and a PE or PP layer; wherein the polyolefin based adhesive contains an organic phase consisting of substantially saturated hydrocarbons, and wherein the adhesive contains amorphous polypropylene, ethylene-propylene copolymers or poly(iso)butylene (co)polymers, said adhesive being flowable when a pressure of 10 kgf/cm.sup.2 is applied, wherein the PE or PP coating is a continuous layer over the coated section, and wherein said polyolefin based adhesive adheres to both the metal pipe and to said PE or PP coating.

An article of apparel including insulation material is discussed. The insulation material includes an insulating layer formed of waterfowl fibers and synthetic fibers. The waterfowl fibers are present in an amount of at least 20% by weight of the insulating layer. The insulating layer is generally free of waterfowl plumage.
