Development of chlorobutyl rubber/natural rubber nanocomposites with montmorillonite for use in the inner liner of tubeless ride tires

Abstract

The aim of this work was to combine the properties of chlorobutyl rubber (CIIR) and natural rubber (NR) in a binary blend for application in the inner liner of tubeless tires, using organomodified montmorillonite (Cloisite^® 15A) as filler in order to improve the barrier property of the material. The maintenance of the mechanical and barrier properties of CIIR/NR 60/40 indicated that this blend can be used in the inner liner of tubeless tires, thereby reducing the cost of the final product, since the CIIR is 80% more expensive than NR.
