  • Rubber masterbatch, method for producing the same, and rubber composition obtained from the same
    Patent number: 10273350
    Abstract: There are provided a rubber masterbatch which can give a vulcanized rubber having a low hysteresis loss while having a low electrical resistance (low volume electrical resistance value); and a method for producing the rubber masterbatch. The rubber master-batch is a rubber masterbatch including a diene rubber, a carbon nanotube, and a silane coupling agent, and the carbon nanotube shows a weight loss proportion of 10 to 30% by weight in a range from 200 to 600° C. in a thermogravimetry of the carbon nanotube.
    Type: Grant
