Rubber composition comprising suitable filler and suitable cross-linking system

The invention relates to a rubber composition based on an elastomer matrix comprising from 40 phr to 80 phr of at least one butadiene elastomer, a vulcanization system comprising sulfur and a vulcanization accelerator, the sulfur/vulcanization accelerator weight ratio being strictly less than 1, and at least 5 phr of an organic filler. The organic filler mainly comprises carbon black, referred to as carbon black G, and has a BET specific surface area in the range of 15 m2/g to 50 m2/g and a compressed sample oil absorption (COAN) in the range of 40 ml/100 g to 100 ml/100 g. 本发明涉及一种橡胶组合物，所述橡胶组合物基于弹性体基质、硫化体系和至少5phr的有机填料，所述弹性体基质包含40phr至80phr的至少一种丁二烯弹性体，所述硫化体系包含硫和硫化促进剂，其中硫/硫化促进剂的重量比严格小于1，所述有机填料主要包含炭黑，所述炭黑被称为炭黑G，并具有在15m2/g至50m2/g的范围内的BET比表面积和在40ml/100g至100ml/100g的范围内的压缩样品吸油值(COAN)。
