Patent ID: 7902285

Claim:
Sulfur-vulcanizable rubber mixture without aromatic process oils formed by combining at least the following: (a) at least one diene rubber; (b) 5-100 phr (parts by weight, relative to 100 parts by weight of the total rubbers in the mixture) of at least one carbon black with an iodine adsorption number of 100-180 g/kg and a DBP number of 100-150 cm 3 /100 g; (c) 5-80 phr of at least one mineral oil plasticizer that has a content of polycyclic aromatic compounds determined with the DMSO extract according to the IP 346 method of less than 3% by weight relative to the total weight of the mineral oil plasticizer; and (d) 5-30 phr of a coumarone-indene resin with a weight-average molecular weight determined with GPC of 250-300 g/mol and a softening point (ring and ball according to ASTM E 28) of less than 40° C.
