DESCRIPTION

Ethylene Bis Stearamide is typically supplied as a white to off-white waxy powder, flakes, or beads with a mild fatty odor.
Ethylene Bis Stearamide is a high-melting bis-amide derived from stearic acid and ethylenediamine, producing a highly crystalline wax-like solid.
Ethylene Bis Stearamide functions as a lubricant by reducing internal friction in melts and as a surface slip agent by migrating in controlled amounts to the surface.

Ethylene Bis Stearamide improves mold release by forming a thin lubricating film that reduces adhesion to metal tooling.
Ethylene Bis Stearamide can improve pigment dispersion by aiding wetting and reducing agglomeration during compounding.
Ethylene Bis Stearamide can provide anti-block behavior in films by reducing surface-to-surface adhesion and improving handling.

Ethylene Bis Stearamide performance depends on dosage, polymer type, processing temperature, shear history, and compatibility with other additives.
Ethylene Bis Stearamide can bloom at high dosages or under certain conditions, so formulation optimization and testing are important.
Ethylene Bis Stearamide should be stored dry and cool to maintain flowability and to prevent contamination during handling.
