EFFECTS OF KAOLIN CONCENTRATION AS FILLER ON VULCANIZATION OF RUBBER YARNS

Abstract

Abstract. A study has been conducted by mixing kaolin and titanium dioxide (TiO₂) used as a filler on latex compounds which have been concentrated in the manufacture of rubber yarns with kaolin variations of 0; 6; 12; 15. This research was conducted to find out the result of kaolin concentration effects on rubber yarns vulcanization. The results showed that the concentration of kaolin mixed with titanium dioxide (TiO₂) affect on rubber yarns vulcanization. The higher the concentration kaolin the smaller the swelling, so the time of vulcanization will take longer.
