| Function: Peptizer for natural and isoprene rubber as well as for their blends with other synthetic rubbers; processing promoter for synthetic rubber; activator with delayed action Use: Aktiplast T has got a lower melting range than Aktiplast PP. It becomes effective in natural and isoprene rubber at a mill temperature of 60 °C. Since Aktiplast T is soluble in rubber, a homogeneous breakdown is achieved without the risk of blooming. Aktiplast T prolongs the scorch time and serves as a dispersing agent for all fillers. Owing to its zinc content, Aktiplast T activates the vulcanization. The addition of stearic acid is not necessary, a reduction of zinc oxide is possible. Aktiplast T reduces the mixing time and improves the flow characteristics of the uncured compound. Aktiplast T has no adverse effect on rubber-to-metal bonding. Aktiplast T improves the storage stability, which is of particular advantage in direct vulcanization. Application: Molded and extruded goods of all types, expanded rubber articles, solid rubber. Peptizing effect in NR and IR above 60 °C. Retards scorch and accelerates vulcanization.
