Laminated self sealing strip for tyres - with plasticised unvulcanised rubber core and vulcanised rubber covers

摘要

Laminated self-sealing for tyres consists of =1 layer of soft rubber sealing material between separating-cover layers of vulcanised rubber, the soft rubber, e.g. ethylene-propylene-diene rubber, being different from the vulcanized rubber, e.g. nitrile rubber, and contg. a plasticiser which does not swell the vulcanised rubber, e.g. a hydrocarbon oil.
