<p>Method for preparing cellular expanded rubber material from expandable rubber mixture is claimed in which said mixture is subjected to at least operations of wringing, crosslinking and expansion; crosslinking and expansion taking place simultaneously and continuously in a horizontal plane. Method for preparing cellular expanded rubber material from expandable rubber mixture is claimed in which said mixture is subjected to at least operations of wringing, crosslinking and expansion; crosslinking and expansion taking place simultaneously and continuously in a horizontal plane; said mixture has Mooney index = 40-80 at 50 degrees C; and said mixture comprises, in addition to rubber, at least a crosslinking system and at least an expansion system both of which are active at the same temperature between 150 and 210 degrees C.</p> |
