NEW ADVANCES IN ELASTOMER NANOCOMPOSITE TECHNOLOGY
Nanocomposite technology offers the potential to provide a platform for the next incremental improvement in tire performance. The adoption of new technology materials by the tire and rubber industry has led to many product performance improvements Tire performance improvements in the last 15 years have been dramatic. Significant enhancements in tire tread wear and traction, reductions in rolling resistance, and improvements in durability have enabled products of high quality. For example, in the 1970s new technology carbon blacks such as N121 and N234 for tread compounds, led to improvements in tread wear. In the 1980s the expansion of the use of SiCl_4 and TiCLi coupled solution SBR allowed reduction in tire rolling However, there have been very few significant changes to the composition of the tire innerliner since the introduction of bromobutyl rubber, Tire innerliners based on nanocomposites may allow liner gauge adjustments and permeability reductions with potential improvements in tire casing durability and, for example, reductions in truck fleet tire casing attrition rates. Nanocomposites based on brominated isobutylene p-methylstyrene copolymers with organically modified layered silicates enable permeability reductions not possible with conventional halobutyl elastomers and filler systems., can also influence other parameters such as fatigue and cut growth resistance and viscosity. This paper is part of an on-going efforts in developing isobutylene polymer nanocomposite for tire innerliner application. Many material properties that influence the innerliner gas permeability and tire performances will be discussed in the presentation.
