Application of Jingangsu in Rubber as Reinforcing Filler

Application of Jingangsu in rubber as reinforcing filler was investigated.When Jingangsu was used to replace carbon black N660 at equal weight in the standard NR or SBR formula,the rebound and flexibility of compound were improved.In tire sidewall compound,it could be used to replace up to 10 phr of carbon black N375;and in inner liner compound,it could replace up to 30 phr of carbon black N660.
