发明名称 Expandable Bladder
摘要 An expandable bladder for manufacturing pneumatic tyres is used in combination with a vulcanisation apparatus including, for example, a mould having a plurality of sidewall plates and tread sectors that, when the mould is closed, delimit a moulding cavity suitable for housing the green pneumatic tyre to be cured. The expandable bladder includes an elastomeric material obtained by curing an elastomeric composition which includes at least one butyl rubber and at least one compound having at least one double bond and an at least partially fluorinated alkyl or polyoxyalkylene chain.
