Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. Polyurethane primer coatings and polyurethane top-coatings are applied to the thermoplastic polyurethane cover. Different coating methods can be used. Isocyanate-rich and polyol-rich polyurethane coatings can be applied. In one embodiment, the golf ball can be treated with a multi-functional isocyanate prior to applying the coatings. The polyurethane cover composition and surface coatings can further include catalysts, ultraviolet (UV)-light stabilizers, and other additives. Heat is used to cure the coatings. The coating methods have many benefits and the finished balls have good physical properties.

Class-A components (CAC) include a first and second skin layer each having a polymer matrix and a fiber reinforcing material embedded within the polymer matrix, a third layer disposed between the first and second skin layers and including a third polymer matrix and a filler material interspersed within the third polymer matrix, and a Class-A finish coat applied to the second skin layer. The fiber reinforcing materials include a plurality of substantially aligned carbon fibers and a plurality of low strength regions staggered throughout the carbon fibers. The CAC can be integrated with a rigid vehicle frame. The CAC can be a structural component. The CAC can be a door, a roof panel, or a hood. The CAC can include a layer of woven fibers between the Class-A finish coat and the second skin layer and a portion of the woven fibers can be visible through the Class-A surface layer.

The first component comprises Polyester Resin (25-40%), Glass Fiber (15-25%), Styrene Monomer (<20%) and Inorganic Filler (25-40%). The second component comprises Acrylic Adhesive (75-95%) and Non-Woven Fabric (5-25%).

A composite cooling film includes a reflective microporous layer that comprises a continous phase comprising an organic polymer, an ultraviolet-absorbing layer of organic polymeric material that is disposed outwardly of the reflective microporous layer, and an anti soiling layer being disposed outwardly of the reflective microporous layer.

A bioelectrode (1) includes: a main electrode film (3); a nonpolarizable electrode film (4) disposed on one surface of the main electrode film (3); and a conductive gel film (5) disposed on the opposite surface of the nonpolarizable electrode film (4) from the main electrode film. The nonpolarizable electrode film (4) is constituted by an electrode film that contains supported silver chloride, the supported silver chloride including (i) a support and (ii) silver chloride supported on the support.

A block copolymer including a polymer block (A) containing more than 70 mol % of a unit derived from an aromatic vinyl compound, and a polymer block (B) containing 30 mol % or more of a unit derived from a conjugated diene compound is provided. The block copolymer satisfies the conditions: (1): a content of the polymer block (A) in the block copolymer is 1 to 70% by mass; (2): a maximum width of a series of temperature regions where tan δ measured in accordance with JIS K7244-10 (2005), under conditions including a strain amount of 0.1%, a frequency of 1 a measurement temperature of −70 to 100° C., and a temperature rise rate of 3° C./min, is 1.0 or more is less than 16° C.; (3): a temperature at a peak position of tan δ in the condition (2) is 0° C. to +50° C.; and (4): a mobility parameter M indicating a mobility of the polymer block (B) is 0.01 to 0.25 sec.

An acrylic multilayer foil includes a layer A in which silica particles are uniformly distributed in an acrylic polymer matrix and a coating layer D. Due to adhesive promoting properties of the layer A containing silica particles, the coating layer D can be advantageously applied onto the layer A. The foil has a high weathering resistance and excellent mechanical properties. Therefore, the foil is highly suitable for surface-protection of materials such as polyvinyl chloride (PVC) and for use in high-pressure laminates (HPLs).

A structural member including a lightweight core, one or more skins, and a crosslinking nanolayer interposed therebetween that results in significant mechanical strength in the structure. The core is a polymer of reduced density by way of included voids, such as an open or closed cell foam, honeycomb, or corrugated structure. The core polymer has a lower density and may have a higher softening or melting temperature than the polymer skin materials. The core may be discontinuous at the interface with the skin such that only a small percentage of the core surface is actually in contact with the skin compared to the overall area of the interface. The skin may be a thermoplastic layer that attaches to the core material. The skin may be a composite material including non-thermoplastic reinforcements. The crosslinking nanolayer is covalently bonded to the surface of the core material and provides molecular compatibility with the skin material.

The present disclosure relates generally to roofing elements and methods for making them. In one embodiment, the disclosure provides a roofing element in the form of a roofing shingle that includes a body of a foamed cured cross-linked polymer, the body having a top surface and a bottom surface, the body extending substantially in a plane and having a thickness in the range of 0.5 mm to 35 mm; and a layer of weather-resistant roofing granules disposed on and adhered at the top surface of roofing element. The roofing element can be made by providing a body of wet foamed curable composition, and allowing the curable composition to cure to provide the body of foamed cured cross-linked polymer.
