Abstract
Erucamide is a fatty acid amide most frequently used to reduce the coefficient of friction (increase slip) of polyolefin films. The erucic acid content of commercial erucamides varies from 80 to 94%. A project has been initiated to determine the effect, if any, that this variation has on slip properties. The performance of erucamide is measured in: • three different butene copolymer linear low-density polyethylenes (LLDPEs) • a hexene copolymer LLDPE • three different low-density polyethylenes (LDPE) Slip is measured on a 1.3 mil blown film. Varying the percentage of erucic acid in erucamide between 80 and 93% did not affect the coefficient of friction in the polymers tested.
