RUBBER VULCANISATES WITH LOW HARDNESS, PROCESS FOR PREPARING RUBBER VULCANISATES HAVING A SHORE A HARDNESS LESS THAN 65 DEGREES, CHARACTERIZED BY A REDUCED TRANSFORMATION OF HEAT ENERGY DURING DYNAMIC DEFORMATION, AND COMMERCIAL RUBBER COMPOSITIONS AND TYRES

摘要

Rubber vulcanisates based on mixtures which contain at least 55% of active fillers and at least 10% of plasticizing oils, having Shore A hardnesses of below 65 DEG in which the active filler contains inorganic active fillers and 10 to 60% of phenolic resin systems consisting of novolaks and hardeners therefor, all these percentages being based on the weight of the rubber, the weight ratio of active inorganic fillers to the phenolic resin systems being from (9:1) to (1:9); the invention further relates to a process for producing such vulcanisates and rubber articles and tires produced from said vulcanisates.
