STRUKTOL® EF 44 A is a newly designed processing additive for applications in natural and synthetic rubber. Due to its selected composition comprising fatty acid derivatives with different polarities, STRUKTOL® EF 44 A provides excellent improvement of processing behavior for a wide range of elastomers like NR, SBR, and EPDM (except for halogenated elastomers).
STRUKTOL® EF 44 A is especially suited for applications in extruded compounds, but also offers advantages on transfer molding and injection molding. STRUKTOL® EF 44 A improves dispersion of fillers (especially mineral fillers) and has a beneficial influence on batch-to-batch uniformity. Finally, STRUKTOL® EF 44 A acts as a cure activator and allows for reduced dosage of stearic acid.
STRUKTOL® EF 44 A is in accordance with regulations FDA 177.2600 and BGA XXI (watch for maximum zinc concentration in rubber compound).
