- 摘要：
- PURPOSE: Provided is a rubber composition for under-tread, which has improved heat conductivity and can shorten the vulcanizing time, therefore can prevent the performance deterioration caused by the property deterioration of tread rubber and improve productivity. CONSTITUTION: The rubber composition for under-tread contains a natural rubber or a synthetic rubber of a natural rubber and a butadiene rubber, as a raw rubber, and additives such as a processing aid, zinc oxide, stearic acid, a processing oil, and 5-40pts.wt.(based on the raw rubber) of an acetylene black and 20-50pts.wt. of a carbon black which is N351 or N550.
