Abstract:
      Using brominated butyl rubber（BIIR） and polyamide（PA） as main materials，dynamically vulcanized BIIR/PA thermoplastic elastomer（TPV） film was prepared，and its properties and application were studied. The results showed that BIIR/PA TPV film had high elongation at break，good tensile fatigue resistance and hot air aging resistance and excellent gas barrier property，which was particularly suitable for tire inner liner. When the TPV film and transition layer film were compounded as inner liner，the durability， low pressure performance and high speed performance of the trial tire met the requirements of national standards，and the mass was reduced by more than 5%.
