The effect of 3M Dynamar FX5911processing additive on butt welding of pipes based on HDPE and the processability of extrusion

Abstract

The use of 3M Dynamar processing additives based on fluoropolymers in the production of pipe grades HDPE allows to signifi cantly reduce the load on the screw and the pressure on the die, providing increase the productivity of the extrusion line. Conducted studies have shown that the addition of Dynamar FX5911, even at high concentrations, does not affect significantly the physicomechanical properties of HDPE and does not impair the strength of the weld when butt welding HDPE pipes.
