| Abstract: |
| Brominated butyl rubber（BIIR）/polyamide（PA） thermoplastic vulcanizate（TPV） film（referred to as TPV film） was prepared.The tensile properties，heat air aging resistance，gas barrier performance，tensile fatigue resistance and microstructure of the TPV film were studied，and compared with those of traditional tire rubber（BIIR） innerliner compound.The results showed that TPV film used as a tire innerliner material had better heat air aging resistance，gas barrier performance and tensile fatigue resistance than those of rubber innerliner compound.Its innerliner thickness was less than 10% of the rubber innerliner thickness，which was an ideal lightweight material for tire. |
