Ethylene Bis-Stearamide

Internal Lubrication

Molecular friction within the polymer melt is reduced when this additive is present. By lowering the viscosity of the resin, ethylene bis-stearamide allows for lower processing temperatures and shorter cycle times. This reduction in heat helps preserve the base properties of the polymer.

Melt Flow

Consistency in the extrusion process depends on the uniform distribution of the lubricant. Adding ethylene bis-stearamide prevents the polymer from sticking to the screw and barrel, which reduces the risk of material degradation and black specks. A cleaner barrel leads to less downtime for maintenance.

Part Appearance

Surface finish and gloss are enhanced by the presence of this wax at the interface of the mold and the melt. Small amounts of ethylene bis-stearamide ensure that complex parts with deep ribs can be ejected without stress whitening or distortion.
