A method for forming a plurality of panels, which may comprise cutting a plurality of Polyurethane (PU) layer cutouts corresponding to a respective shape for each of the plurality of panels from a sheet of PU, placing each of the plurality of PU layer cutouts in a corresponding mold, forming each respective panel in each respective corresponding mold by injecting melted TPE into each of the corresponding molds for thirty to forty seconds, and creating a bladder valve panel by inserting a valve in one of the plurality of created panels. Method may further comprise forming a pre-finalized ball by attaching the plurality of the panels including the bladder valve panel to a bladder and respective edges to each of the plurality of the panels to respective edges of adjacent panels of the plurality of the panels, and placing the pre-finalized sports ball in a mold and applying heat to the pre-finalized sports ball.

A method for forming polyurethane foams for vehicle seat components in a molding apparatus is provided. The method includes a step of directing one or more polyol compositions into a mold. Each of the one or more polyol compositions includes a polyol, water, and a catalyst. The method also includes a step of directing an isocyanate composition into the mold, the isocyanate composition including one or more isocyanates. The one or more polyol compositions and the one or more isocyanates are combined into a reaction composition that forms a foamed vehicle seat component. Characteristically, the mold has a shape that defines a foamed vehicle seat component. Characteristically, either the one or more polyol compositions and/or the isocyanate composition includes a liquid antimicrobial agent that is a liquid at temperatures above 10 C.

The invention relates to a method for producing a foam-backed molded component, the method comprising the following steps: a) introducing a cover material in a mold (100), the mold (100) having a negative-profiled surface (310); and b) generating and maintaining a vacuum and/or negative pressure on the side of the cover material facing the mold (100); and c) pouring a foam material in the mold (100); and d) closing the mold (100); and e) molding the foam material; and f) opening the mold (100) and removing a foam-backed molded component, the foam-backed molded component having a profiled surface.

A method of forming an implantable biomaterial comprising the steps of providing a polyether-diisocyanate prepolymer, reacting the prepolymer with one or more chain extender molecules typically including benzene 1,4-diol to form a mouldable polymer selected from a polyurethane or polyurethane-urea polymer or a polyurethane-urea block copolymer; placing the mouldable polymer into an implantable biomaterial shaped mould, and shaping and curing the mouldable polymer in the implantable biomaterial shaped mould to form the implantable biomaterial. An implantable biomaterial such as a heart valve leaflet is also disclosed.

A coated lens has a stamping which contains one or more ring-shaped focusing structures. A method for manufacturing such a coated lens is provided in which a coating composition is stamped. The coating composition includes at least one of an epoxide component and a (meth)acrylate component. The ring-shaped focusing structure(s) provide an additional power compared to the central clear zone of the coated lens.

The present disclosure is relates to a TPU ball structure and a manufacturing method thereof. The TPU ball structure includes a ball bladder layer, a yarn layer and a surface layer. The ball bladder layer is made of TPU material. The yarn layer is made of TPU material, and the yarn layer is disposed to cover the ball bladder layer. The surface layer is made of TPU material, and the surface layer is disposed to cover the yarn layer. The above layers of the TPU ball structure are made of TPU material to satisfy a requirement for environmental protection, and are recyclable. There is no need to use adhesive to adhere the above layers of the TPU ball structure. Therefore, the peeling strength between the layers of the TPU ball structure can be increased so that the whole peeling strength of the TPU ball structure can be increased.

A high-ageing-stable planar sheet for the building sector and to the use of a high-ageing-stable planar sheet in the building sector, in particular as a sarking sheet, underlay sheet and/or sheathing sheet in a roof construction and/or a faade sheet in a wall construction.

A plastics cover for a motor vehicle includes a visible side, an inner side, and a carrier side. The carrier layer is composed of a transparent polymer material, which has a continuous and constant basic wall thickness and at least one of an arrow-shaped, tetrahedral, pyramidal, conical, or cuboidal recess at which at least one wall thickness variation is formed on the inner side of the carrier layer. The finishing layer which is arranged on a visible surface of the carrier layer. The finishing layer comprises a transparent polymer material.

A resin film-laminated metal sheet includes a metal sheet and thermoplastic resin films that are fused to both surfaces of the metal sheet, the metal sheet is a steel sheet having a thickness of 0.08 mm or more or an aluminum sheet having a thickness of 0.15 mm or more, and, when a surface of the thermoplastic resin film opposite to a surface that is fused to the metal sheet is defined as a first surface, the surface tension on the first surface in at least one of the thermoplastic resin films is 50 mN/m or less, the surface tension on the surface that is fused to the metal sheet is 36 mN/m or more, and the amount of a wax attached to the first surface is more than 0 mg/m.sup.2 and 5.00 mg/m.sup.2 or less.
