1、It is an ideal lubricant of LLDPE and HLPE in extruding that can up speed of extruding and make products surface smooth and polish. Particularly, LLDPE in blowing mold that can improve appearance quality and transparency of film and avoid phenomenon of sharkskin. 2、Blending with PP resin,it can be modifier and mould releaser.Due to added a great deal of fillings in the process of PP that caused extruding hardly,products surface rough and products hard to release from mould.Adding suitable PP wax(depend on products,usually 7~8%) that can improve fluidity of the blending and make mate-rials melted and dissolved mutually,and make products easy to releasefrom mould and enhance products appearance polish obviously. 3、PP wax can substitute PE wax for manufacturing of high temperature filature master batch and it overcome disadvantage of PE wax under high temperature makeflature easy to sublime with peculiar smell.
