Abstract

The innerliner for a tire has excellent impermeability, air retention and good flex properties. The innerliner offers a role to improve performance parameter, such as air retention and tire durability that is of praricular importance for commercial tires. In order to improve the gas barrier properties of a innerliner, most of the innerliner rubbers, such as a halogenated butyl rubber(HIIR), brominated poly(isobutylene-co-isoprene)(BIIR), brominated polyisobutylene-co-paramethylstyrene(BIMS) are used as nanocomposites with nano fillers such as silicates, graphite etc. Innerliners based on nanocomposites may allow gauge adjustments and permeability reductions with potential improvement in tire durability. This article discusses potential innerliner permeablity reduction and compounding parameters on the properties of nanocomposite based innerliners.
