Title (EN) RUBBER COMPOSITION COMPRISING A PLASTICISING SYSTEM BASED ON A BLEND OF HYDROCARBONATED RESIN HAVING A LOW AND A HIGH GLASS TRANSITION TEMPERATURE
(FR) COMPOSITION DE CAOUTCHOUC COMPRENANT UN SYSTEME PLASTIFIANT A BASE D'UN COUPAGE DE RESINE HYDROCARBONEE DE FAIBLE ET DE HAUTE TEMPERATURE DE TRANSITION VITREUSE
Abstract: front page image
(EN)The invention relates to a rubber composition based on at least one diene elastomer, a reinforcing filler, a vulcanisation system and a combination of plasticisers, said combination of plasticisers comprising more than 15 pce (parts by weight per hundred parts of elastomer) of hydrocarbonated resin having a glass transition temperature (Tg) of between -40°C and 20°C and a resin having a Tg higher than 20°C, the total amount of plasticiser being higher than, or equal to, 40 pce, and the amounts of reinforcing filler and plasticiser being such that the ratio of the total amount of filler and the total amount of plasticiser ranges between 1.3 and 2.
(FR)L'invention concerne donc une composition de caoutchouc à base d'au moins un élastomère diénique, une charge renforçante, un système de vulcanisation et une combinaison de plastifiants, ladite combinaison de plastifiants comprenant plus de 15 pce (parties en poids pour cent parties en poids d'élastomère) de résine hydrocarbonée de température de transition vitreuse (Tg) comprise entre -40°C et 20°C et une résine de Tg supérieure à 20°C, le taux total de plastifiant étant supérieur ou égal à 40 pce et les taux de charge renforçante et de plastifiant étant tels que le rapport du taux total de charge et du taux total de plastifiant est compris dans un domaine allant de 1,3 à 2.
