Tubeless tyre inner liners morphology and physical - Properties of elastomeric blends

Cure kinetics, morphology and gas permeability constants of CIIR/NR, BIIR/N R blends were examined as functions of elastomer viscosities. Scorch time a nd mixing extent decrease on increasing the viscosity of the components; sc orch time is also negatively affected by the presence of BIIR in the blend. Values of gas permeability constant of the blends do not linearly depend o n the composition and are affected by the viscosity of the components, whic h determines the morphology and the carbon black distribution in the blend.
