Acmetol 44

Composition Mixture Of Zinc And Alkali Soaps Derivatives

It is used as a dispersing aid, flow promoter and cure activator, suited for NR and synthetic rubber like SBR and EPDM(except for halogenated elastomers). Improves dispersion of mineral fillers and carbon black, providing uniform viscosity from batch-to-batch, suited for applications with extruded compounds but also offers advantages in transfer molding and injection molding. It also acts as a cure activator, therefore dosage of stearic acid has be reduced in compound recipe(1 to 3 phr).

Recommendations For Application

ACMETOL -44 i s a newly designed processing additive for applications in natural and synthetic
rubber. Due to its selected composition comprising fatty acid derivatives with different polarities,
ACMETOL-44 provides excellent improvement of processing behavior for a wide range of
elastomers like NR, SBR, and EPDM (except for halogenated elastomers).
ACMETOL-44 is especially suited for applications in extruded compounds, but also offers
advantages on transfer molding and injection molding. ACMETOL-44 improves dispersion of
fillers (especially mineral fillers) and has a beneficial influence on batch-to-batch uniformity.
Finally, ACMETOL-44 acts as a cure activator and allows for reduced dosage of stearic acid.
