Acmetol 44

ACMETOL EF 44 is an excellent flow promoter for rubber compounds with high level of white fillers, namely, silica, chalk, clay, etc. It could be used as a process additive for all kinds of polymers / rubbers. It improves dispersion of fillers (especially minerals fillers) and has beneficial influence on batch-to-batch uniformity. It decreases the tendency of re-agglomeration of silica. It is suitable for better extrusion and could be suitable for compression, transfer and injection moulding applications. It could be useful as processing aid in the production of radial tires, rubber belts and cables. Suitable for all kinds of non-halogenated elastomers. ACMETOL EF 44 can be added at any stage of the mixing cycle.

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.

Dosage
