Precipitated Silica (white carbon black, sole making) WL-180

WL-180 has special physical and chemical properties. It is the best transparent reinforcement additive in mixture directons based in rubber, greatly improves tensile strength and abrasion resistance of vulcanized rubber, saving the usage of rubber and reducing the production cost. It is with good appetency which make it has good dispersive ability in raw glue. Physical appearance come into being that 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. It is a highly reinforced filling agent for rubber.
