ELASTOMERIC COMPOSITION FOR A TIRE OBJECT HAVING A SELF-SEALING PROPERTY

摘要

The invention relates to an elastomeric composition having a self-sealing property, which is usable, in particular, as an anti-puncture layer in a tire object, and containing at least (a significant percentage of parts by weight percent of a solid elastomer): an unsaturated solid diene elastomer; between 30 and 90 percent of a hydrocarbon resin; 0 to less than 30 percent of a filler; between 0.5 and 15 percent of thiuram polysulfide. The invention also relates to a pneumatic object such as a pneumatic tire provided with an anti-puncture layer including a composition according to the invention; the anti-puncture layer is advantageously associated with an air-tight layer, e.g., containing butyl rubber or a TPS elastomer, in order to form an air-tight and anti-puncture laminated composite in the pneumatic object.
