Acmetol 50

Acmetol 50 by Acmechem is a processing aid and peptizer for natural rubber, lubricant and flow promoter. It improves reversion resistance and produces vulcanizates with greater resilience and tear strength. It can be used without blooming or adverse effect on rubber-to-metal or rubber-to-rubber adhesion. Due to the polymer chain lubricating effect, compounds containing Acmetol 50 exhibit lower viscosities under shear as well as enhanced flow rates, which improves mill roll release and provides smoother extrusion and calendaring. Recommended dosage level is 3 to 5 phr. It has a shelf life of 18 months.
