Recommended Applications: One of the major uses of oleamide is as a slip agent in polyethylene films. It functions by migrating to the film surface in a microscopic coating which reduces the coefficient of friction. In general, oleamide migrates more rapidly than erucamide (STRUKTOL® TR 131) but has lesser heat stability. Where this is not a disadvantage, oleamide costs are inherently lower.

This same property of uniform surface bloom permits STRUKTOL® TR 121 to be used in injection molding applications. It functions as both a lubricant and mold release agent. These properties are valuable in processing thermoplastic resins, thermoplastic elastomers (TPEs) and thermoset rubber systems. STRUKTOL® TR 121 may also function as a dispersant in concentrates by providing easier and more uniform letdown of the concentrated material. STRUKTOL® TR 121 is insoluble in water and has limited solubility in alcohols, ketones and aromatic solvents.
Dosage Level: Applications in the rubber area normally require 1 - 3 phr loading levels.

For plastics, these loadings may vary from around 0.05% in films to more than 0.5% in mold release applications.

For PVC 0.05 - 0.6 %.
