Internal Liner Air Retention (IIR/CIIR Blends)

1. The Industrial Challenge

Maintaining consistent inflation pressure is key to preventing sidewall fatigue and excessive heat build-up. This bulletin addresses the optimization of the inner liner compound using Chlorobutyl (CIIR) or Bromobutyl (BIIR) blends to minimize air permeability. Improving the air retention properties of the liner by 40% ensures that the tyre remains ...
