ACMETOL WB 16 is used in rubber compounds to improve the flow properties. This effect is attributable to a considerable reduction of the viscosity (internal friction) of the green compound and a decrease of the sliding friction when in contact with metal surfaces. The release effect of ACMETOL WB 16 is remarkable. ACMETOL WB 16 eliminates sticking to rotors in internal mixers or on open mills and calender rolls, and improves mold release, especially when complicated mold designs are involved. ACMETOL WB 16 has a slight activating effect on the cure rate of sulfur-containing compounds. It is suitable for most of the elastomers like EPDM, IIR, CIIR, BIIR, CR, IR, ACM and BR. ACMETOL WB 16 can be added at any stage of the mixing cycle, even during the warm up stage of the finished compounds prior to calendering. However, to achieve the optimum release effect and reduction of friction, it is best to add the ACMETOL WB 16 during the final mixing stage.
