Abstract
A masterbatch having functionalized silicone with an epoxy group or a secondary amine group as a slip additive, the polyethylene compound that the silicone-containing masterbatch has been let down into, and the plastic articles and films from such compounds having improved slip properties are disclosed. The improved slip properties are evidenced by essentially no migration of the slip additive 12 weeks after manufacturing and a dynamic coefficient of friction value of less than 0.4 and a static coefficient of friction 0.5 or less as measured within the first day of manufacturing according to the ASTM D1894-01 method.
