Title:
RUBBER COMPOSITION
Document Type and Number:
Japanese Patent JPH04209640
Kind Code:
A
Abstract:
PURPOSE:To improve abrasion resistance, prevention of heat buildup, and impact resilience by compounding a rubber component with a specific furnace black. CONSTITUTION:100 pts.wt. rubber component is compounded with 35-100 pts.wt. furnace black having a nitrogen adsorption specific surface area of 60-100m<2>/g and a Bohr's modal diameter (Dp) among aggregates having selective characteristics shown by the formula (wherein Dp is the most probable modal diameter in the Bohr's diameter distribution among aggregates measured by differential scanning calorimetry; and Dst is a Stokes' modal diameter of aggregates measured with a disc centrifuge) and other necessary ingredients such as a vulcanizing agent, an accelerator, an antioxidant, a vulcanization aid, a softener, and a plasticizer.
