RUBBER COMPOSITION FOR TIRE TREAD

摘要

PURPOSE: To obtain a rubber composition for tire treads capable of improving the performances of a pneumatic tire on the ice without deteriorating the abrasion resistance or processability. CONSTITUTION: This rubber composition for tire treads is obtained by blending >=10 pts.wt. silica, <=60 pts.wt. total filler and 0.5-15 pts.wt. staple fibrous material having <=20μm average diameter and <=2000μm average length with 100 pts.wt. at least one rubber among natural rubber, polyisoprene rubber and polybutadiene rubber.
