Silicon Dioxide

Silicon Dioxide Silicon Dioxide NL180 NL180 has especial physical and chemistry properties which it has best transpatent additive in mixture directions based in rubber,greatly improve tensile strength and abrasion resistance of sulfuration rubber, reduce dosage of rubber, fall cost. WL-180 has stronger appetency, make it bear biggish dispersive ability in fresh glue, physical appearance come into being that white carbon black grain and rubber molecule, excelled white carbon black in boosting up engine intension of rubber and reinforcement of tear. Highly reinforced filling agent of rubber. Application for tint,colour,transparent rubber produce.
