 | Why use Slip Masterbatches : Polyolefin films tend to conform to themselves and with the metal surfaces owing to their high coefficient of friction (COF). For processing ease, these films need a COF near 0.2. These masterbatches lower the friction between film layers and other surfaces. In order to be effective the slip requires tomigrate to the surface and therefore requires a certain degree of incompatibility with the polymer. Action of Slip Masterbatches : Fatty acid amides find application as slip additives. During processing these masterbatches are solubilized in the amorphous melt, but as the cooling of the polymer occurs the fatty acid amide is “squeezed” out forming a lubricating layer at the polymer surface. Addition of slip additive thus gives easy slippage of film over other surfaces. AddKan Slip Masterbatches : AddKan Slip additive masterbatches are based on highly pure euracamide – a slow slip additive. Films made with slow slip additives should be printed immediately after they are made as later on Slip additives may hinder with adhesion of lamination films or printing inks. Normal addition levels vary between 1-3% depending upon desired reduction in COF or reduction in surface roughness.
