Multi-piece golf balls having a solid core and cover are provided. The ball contains a small, heavy inner core and surrounding outer core layer. The inner core preferably contains metal powder such as copper, steel, brass, tungsten, titanium, nickel, iron, tin, and bronze particles dispersed in a thermoset or thermoplastic polymeric matrix. For example, a polybutadiene rubber matrix may be used. In one preferred embodiment, the inner core contains elemental iron powder. Preferably, the particles have a weight average size in the range of about 10 μm to about 450 μm. In one embodiment, the outer surface of the inner core has a structure with projecting members. For example, the outer surface may contain multiple projecting ribs with gaps located between the ribs. The ball includes a cover surrounding the core structure. The cover may be multi-layered.

Embodiments relate to a method for manufacturing a heat-shielding film in which a heat-shielding material has been well dispersed in a polyvinyl chloride resin. According to one embodiment, the method for manufacturing the heat-shielding film includes (1) mixing a polyvinyl chloride resin composition (P) containing the polyvinyl chloride resin (A) using a blender, and (2) adding and further mixing the heat-shielding material with the mixture obtained in step (1 The heat-shielding material contains at least antimony-doped tin oxide micro-particles (B) in an amount in which the mass ratio of the polyvinyl chloride resin (A) to antimony-doped oxidized tin micro-particles (B) is 100 parts by mass to 1.5 to 15 parts by mass. The heat-shielding material is composed of antimony-doped oxidized tin micro-particles (B) alone.

Provided is an insulating tape to be used in a nonaqueous secondary battery, the insulating tape being capable of maintaining its insulating property even under a severe environment, e.g., even when being heated, and being capable of improving the safety of the nonaqueous secondary battery. Specifically, provided is an insulating tape for a nonaqueous battery, including a base material, and a pressure-sensitive adhesive layer arranged on one side, or each of both sides, of the base material, in which the base material and/or the pressure-sensitive adhesive layer each contain/contains an insulating inorganic filler. Also provided is an insulating tape for a nonaqueous battery, including a base material with an insulating layer, and a pressure-sensitive adhesive layer arranged on one side, or each of both sides, of the base material with the insulating layer, in which the insulating layer contains an insulating inorganic filler.

There is provided a one-pack type room-temperature-curable 2-cyanoacrylate based composition having magnetism.
