| 摘要 |
The invention concerns rubber compounds consisting of at least one double bo nd- containing rubber and additions of polybutadiene rubber particles having a glass transition temperature <-60.degree.C together with vulcanisates and rubbe r mouldings manufactured therefrom. The rubber compounds according to the invention are characterised in th e uncrosslinked state by good processability and adequate scorch resistance an d in the vulcanised state by high Shore A hardness, high impact resistance, low hysteresis losses and low heating-up under dynamic stress, together with a low specific density. The vulcanisates are particularly suitable for the manufacture of tyre components for which low heating-up under dynamic stress is required, e.g. for tyre bead an d apex compounds, subtread compounds, tyre carcasses and for tyre sidewalls. The compounds are particularly suitable for the manufacture of reinforced sidewalls for tyres with emergency running properties (inserts for run-flat tyres).</SDOAB >
