Document Type and Number:
Japanese Patent JP6597999
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fender in which buffer performance is superior, a high reaction force is provided even if miniaturized, and further, buffer performance degradation and cracks due to aging are difficult to be caused even if continuously used over a long period of time particularly under high temperature environment.SOLUTION: A fender comprises a carbon black in which a nitrogen adsorption specific surface area is 70-120 m/g and DBP oil absorption is 90-130 cm/100 g of 60-80 pts.mass per 100 total amount pts.mass of a rubber content, the rubber content containing natural rubber, and a crosslinking substance of the rubber composition containing the sulfur. The fender is formed such that the crosslinking density is 5×10to 2×10mol/cm, and a ratio of monosulfide bond occupied in all bridging is 10-50%.SELECTED DRAWING: None
