Elastomeric composition with improved thermal conductivity

摘要

A rubber composition based on at least one diene elastomer, a filler that contains carbon black and an inorganic filler, and a crosslinking system, wherein the inorganic filler content is greater than or equal to 5 parts by weight per hundred parts by weight of elastomer, phr, and represents at most 50% as a weight fraction of the whole of the total filler of the composition, and wherein the carbon black includes at least one acetylene-derived carbon black, with a content of greater than 3 phr, the amount of acetylene-derived carbon black representing more than 50% of the carbon black present in the composition as a weight fraction, and wherein the composition contains a plasticizing oil or a plasticizing resin with a total content of plasticizing oil and plasticizing resin of less than 30 phr.

1. A rubber composition based on at least one diene elastomer, a filler that comprises carbon black and an inorganic filler, and a crosslinking system,
wherein the inorganic filler content is from 8 to 30 parts by weight per hundred parts by weight of elastomer, phr, and represents at most 50% as a weight fraction of the total filler of the composition wherein the carbon black comprises at least one acetylene-derived carbon black, wherein the acetylene-derived carbon black content is from 10 to 40 phr, wherein the amount of acetylene-derived carbon black represents more than 50% of the carbon black present in the composition as a weight fraction, and wherein the composition comprises a plasticizing oil, aplasticizing resin, or both, with a total content of plasticizing oil and plasticizing resin of less than 30 phr.
