DEVICE FOR LOWERING THE VISCOSITY OF A SULPHUR-CROSS-LINKED RUBBER MIXTURE, USE OF THE DEVICE AND METHOD FOR PRODUCING A PLASTICIZED SULPHUR-CROSS-LINKED RUBBER MIXTURE

摘要

Device for lowering the viscosity of a sulfur-crosslinkable rubber mixture, comprising a plasticizing unit for plasticizing sulfur-crosslinkable rubber mixtures and a feed unit downstream of the plasticizing unit for feeding rubber mixtures into an extrusion unit, characterized in that the device comprises means for regulating the residence time of a sulfur-crosslinkable rubber mixture in the supply unit. The use of the device and a method for producing a plasticized sulfur-crosslinkable rubber mixture are also disclosed.
