  • LIGNIN-ENHANCED BUTYL RUBBERS
    Publication number: 20210371630
    Abstract: Halogenated butyl rubbers are provided comprising lignins and co-reinforcing agents, where the ratio of the lignin to the co-reinforcing agent is selected so as to effectively modulate advantageous properties of the vulcanizate. The advantageous properties are achieved when using a ratio of lignin to the co-reinforcing agent, such as carbon black or silica, that is higher than in a reference vulcanizate, in effect the substitution of lignin for conventional reinforcing agents improves the reinforcement of the vulcanizates.
