Acmetol 50

ACMETOL 50 is in our series of process additives developed by Finorchem, which are zinc fatty acid derivatives. These zinc salts have proven effective over the years as physical peptizers for natural rubber.  Since the available double bonds act to stabilize free radical formation, products such as ACMETOL 50 improve reversion resistance and produce vulcanizates which display greater resilience and tear strength.  Because of the higher level of solubility, ACMETOL 50 can be used without fear of bloom or adverse effect on rubber to metal or rubber-to-rubber adhesion. Due to the polymer chain lubricating effect, compounds containing ACMETOL 50 will display lower viscosities under shear as well as greatly enhanced flow rates. When used as a process additive for solution SBR, compound viscosities are reduced while flow rates and reversion resistance are improved. ACMETOL 50 will also provide easier mixing and extrusion of compounds based on solution SBR.  Mold flow and mill roll release will also be enhanced. It is suitable for natural and synthetic rubbers. ACMETOL 50 can be added as per standard recommendation.
