Abstract
Slip additives are low viscosity additives, which are compounded to modify the surface properties of polyolefin films and reduce the friction coefficient of the films. In this study, the effects of the slip additives on the rheology of low density polyethylene resins and the mechanical, optical and surface characteristics of blown films were investigated. It is determined that the slip additive remains dispersed in the matrix during flow through the capillaries. At relatively high concentrations the slip additive adversely affects some of the ultimate film properties including tensile strength and haze.
