Title
(EN) TIRE INNER LINER
(FR) DOUBLURE INTERNE DE PNEU
Abstract
(EN)
A tire is provided that has an inner liner with a rubber composition based upon a cross-linkable rubber composition that has per 100 parts by weight of rubber. The tire has a rubber component between 80 phr and 98 phr of a butyl rubber, between 0.5 phr and 15 phr of a polybutadiene rubber and between 0 phr and 20 phr of a polyisoprene. Also present is between 1 phr and 10 phr of a plasticizing resin having a glass transition temperature of at least 25 °C. Also included is between 1 phr and 40 phr of a platy filler, and a curing system.

La présente invention concerne un pneu qui comporte une doublure interne ayant une composition de caoutchouc basée sur une composition de caoutchouc réticulable qui présente pour 100 parties en poids de caoutchouc. Le pneu comporte un composant caoutchouc compris entre 80 phr et 98 phr d'un caoutchouc butyle, entre 0,5 phr et 15 phr d'un caoutchouc polybutadiène et entre 0 phr et 20 phr d'un polyisoprène. La présente invention concerne également entre 1 phr et 10 phr d'une résine plastifiante ayant une température de transition vitreuse d'au moins 25 °C. Sont également inclus une charge lamellaire entre 1 phr et 40 phr, et un système de durcissement.
