AQUEOUS ADHESIVE FOR RUBBER
An aqueous adhesive for rubber of the present disclosure includes: a base agent containing rubber latex as a main component thereof; and an organic solvent that causes swelling of a rubber component in the rubber latex. An amount of the organic solvent in the aqueous adhesive for rubber is not less than 25% by mass and not greater than 60% by mass of a total amount of the base agent and the organic solvent. A boiling point of the organic solvent is preferably not higher than 140° C. A tennis ball of the present disclosure includes a hollow core made of a rubber material. The hollow core includes two hemispherical half cores. The two half cores are adhered to each other by using the aqueous adhesive for rubber.
Polymeric insulating films
Insulating films suitable for use in magnet wire, electrical machines, and other applications may include at least one layer formed from extruded material. The extruded material may include a blend of a first polymeric material and a second polymeric material different than the first polymeric material. The first polymeric material may include one of polyetheretherketone, polyaryletherketone, polyetherketoneketone, polyphenylsulfone, polyphenylene sulfide, or polybenzimidazole, and the second polymeric material may include one of polyphenylsulfone, polyetherimide, polyethersulfone, polyphenylene sulfide, polycarbonate, or polyester.
CURABLE POLYORGANOSILOXANE COMPOSITION AND ELECTRONIC COMPONENT
A curable polyorganosiloxane composition includes (a) a polyorganosiloxane having two or more curable functional groups per molecule; (b) a crosslinking agent having per molecule two or more crosslinkable groups having reactivity with the curable functional groups of the component (a); (c) a curing catalyst capable of catalyzing a crosslinking reaction of the component (a) and the component (b); (d) a pigment which itself does not emit a fluorescent light; and (e) a UV tracer. The composition can be used as an adhesive.
Process for making pressure-sensitive adhesive and duct tape
A continuous process for making a pressure-sensitive adhesive is disclosed. A mixture comprising natural rubber having a Mooney viscosity of 85 to 100, a tackifier, a filler, and 0.1 to 5 wt. % of an added C.sub.12-C.sub.24 fatty acid based on the amount of mixture is masticated in a first section of a single- or twin-screw extruder. Mastication of the mixture continues in at least one subsequent extruder section in the presence of additional tackifier. The product is a homogeneous, reduced-viscosity pressure-sensitive adhesive. The minor proportion of added C.sub.12-C.sub.24 fatty acid aids mastication of the rubber and enables high throughput without addition of peptizers. Duct tapes made from the adhesives display improved adhesion to steel, better adhesion bond strength, and enhanced seven-day clean removability from even difficult substrates such as marble or ceramic tile.
Prosthetic valves, valve leaflets and related methods
Examples herein include prosthetic valves, valve leaflets and related methods. In an example, a prosthetic valve is included having a plurality of leaflets. The leaflets can each have a root portion and an edge portion substantially opposite the root portion and movable relative to the root portion. The leaflets can include a fibrous matrix including polymeric fibers having an average diameter of about 10 nanometers to about 10 micrometers. A coating can surround the polymeric fibers within the fibrous matrix. The coating can have a thickness of about 3 to about 30 nanometers. The coating can be formed of a material selected from the group consisting of a metal oxide, a nitride, a carbide, a sulfide, or fluoride. In an example, a method of making a valve is included. Other examples are also included herein.
