A method for reducing the stickiness on the surface exposed to the air of a sealant layer applied on an inner cavity of a tyre. The method establishes that the surface exposed to the air of the sealant layer is subject to a UV radiation.

The invention relates to an elastomeric article made from a cured product of synthetic latex composition, characterized by a base polymer; a solubilized polyvalent metal hydroxide having a pH above 9.0 at a range of 0.0001 to 0.20 phr; a milled polyvalent metal oxide; an alkali solution for solubilizing the polyvalent metal hydroxide; and fillers at 0.5 phr minimum for manufacturing the elastomeric article with biodegradable properties; wherein said elastomeric article having thickness of 0.001 to 5 mm; tensile strength of 7 MPa; and elongation of 300% minimum. The invention also relates to the method to manufacture the elastomeric article, comprising preparing a former for shaping the elastomeric article; dipping the former into a coagulant solution; drying the coagulant-coated former; dipping the dried coagulant-coated former into a synthetic latex composition to create the elastomeric article; followed by pre-leaching; vulcanizing; surface treating; post-leaching; applying donning aid; drying and stripping the elastomeric article from the former.

A composition for use as a binder system for road marking formulations and methods for making thereof is disclosed. The binder system is provided as pellets. The method provides for making the pelletized binder system, and mixing the pelletized binder system with fillers and other components, heating the mixed ingredients forming into a molten mixture for applying on a road surface. The pelletized binder system comprises at least a resin and an elastomer in one embodiment; at least a resin and a plasticizer in a second embodiment; and at least a resin, an elastomer, and a plasticizer in a third embodiment.

Molded watersports and cold-climate gloves, where a substantial portion of the accessory is molded in a three-dimensional mold with a soft, pliable, and durable material such as EVA (Ethylene Vinyl Acetate) or PU (Polyurethane) or similar foam blends that aid in the flexibility, durability, and comfort of the accessory.

Aspects of the disclosure relate to systems and techniques for inspecting seals for high altitude balloons. In one example, a system may include a reflective surface, a translucent material on the reflective surface, and a movable light source configured to move along the reflective surface and provide light to the reflective surface. The light is provided such that it is reflected from the reflective surface and through the translucent material in order to backlight a balloon envelope seal for inspection. A method for inspecting a balloon envelope seal may include placing balloon envelope material on a table, forming a seal between portions of the material, moving a light over the seal, shining light onto a reflective portion of the table below the seal to backlight the seal, and inspecting the seal using the backlighting of the seal.

The pipe includes at least one tubular sheath delimiting a passage for circulation of the abrasive material, at least one tensile armor layer externally positioned with respect to the tubular sheath, the armor layer including a plurality of filiform armor elements. It further includes a protective internal layer positioned inside the tubular sheath in the circulation passage, the protective internal layer including an elastomeric matrix and a longitudinal reinforcement assembly embedded in the matrix.

Aspects of the disclosure relate to techniques for manufacturing a balloon envelope. In one example, a first sheet of material for a first gore of the balloon envelope is provided. Lap seal material is arranged at least partially on the first sheet of material. A first heat seal is created between the lap seal material and the first sheet of material. A second sheet of material for a second gore of the balloon envelope is arranged over the first heat seal. A second heat seal is created between the lap seal material and the second sheet of material such that the lap seal material is configured to provide additional structural support to the balloon envelope.
