UNVULCANIZED RUBBER COMPOSITION FOR CALENDARING AND METHOD FOR MANUFACTURING TOPPING RUBBER USING THE SAME |
| 摘要 |
An unvulcanized rubber composition for calendaring has an elongational viscosity of not more than 102 kPa when measured at a temperature of 95 deg. C., and a shear velocity of 500 to 2000 (1/second). A method for manufacturing a topping rubber for a cord ply embedded in a pneumatic tire is characterized in that, the unvulcanized rubber composition is extended and shaped with the use of calender rolls whose surface temperature is 60 to 100 deg. C. |

1. An unvulcanized rubber composition for calendaring during which the unvulcanized rubber composition is subjected to elongation deformation by calender rolls and which is characterized by having an elongational viscosity of not more than 102 kPa when measured at a temperature of 95 deg. C., and a shear velocity of 500 to 2000(1/second). |
