Recommendations For Application
ACMETOL 50 is the latest in a series of process additives developed by us which are zinc fatty acid derivatives.
T hese 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.
W hen used as a process additive for solution SBR, compound viscosities are reduced while flow rates and reversion resistance are improved.

M old flow and mill roll release will also be enhanced.
