RUBBER COMPOSITION BASED ON NATURAL RUBBER HAVING A MOLECULAR MASS DISTRIBUTION, SECAMED VIEW, BIMODAL, PROCESS FOR PREPARATION AND PNEUMATIC COMPONENT

摘要

The present invention relates to a rubber composition based on at least: an elastomeric matrix comprising: a rubber composition based on at least: - an elastomeric matrix comprising: natural rubber, a reinforcing filler, a crosslinking system, characterized in that said natural rubber comprises at least 90% by weight, relative to the total weight of natural rubber, of a natural rubber having a molecular weight distribution , seen in SEC-MALS, bimodal. It also relates to a method for preparing such a composition, a tire component comprising it and a tire comprising this component.
