A conformable adhesive article for use as a sterile medical dressing is described. The article includes a breathable polymeric matrix, a plurality of phases, and an adhesive composition positioned on the polymeric matrix. The plurality of phases preferably provide reinforcement and stiffness to the article. The article permits transport of moisture across the breathable polymeric matrix, preferably at an Inverted water moisture vapor transmission rate of at least 300 g/m/24 hours.

Adhesive composite having distinct phases

A die apparatus, a method of using the die apparatus to produce co-extruded polymeric articles, and co-extruded polymeric articles produced using the die apparatus and method are disclosed. The die apparatus includes a hollow vane configured to extrude a material into a chamber within the die, thereby producing a co-extruded web. The co-extruded web has a plurality of distinct, discontinuous phases in the cross-web direction, the phases having a uniform width as shown by a coefficient of variation of less than 8 percent for any three consecutive phases. The phases are substantially continuous down-web and are surrounded by a matrix having two or more layers.

Extrusion die and process

A sporting goods article with a coating on a surface of the article for abrasion resistance and/or a high gloss appearance. The outer layer of the surface is a polymer, wood, metal, non-polymeric ink, non-polymeric colorant, non-polymeric dye, or a combination thereof The coating is a cured ceramer composition. The cured ceramer composition, in its simplest embodiment, is derived from a composition including inorganic oxide particles and a curable organic matrix, with the curable organic matrix including at least one ethylenically unsaturated monomer and at least one organofunctional silane monomer coupling agent.
