Melt fracture is a surface roughness on films, bottles, wire and cable, pipes or other
extruded shapes, resulting from a slip/stick action of molten polymer exiting a die. It is
more often seen with tougher resins such as LLDPE and HDPE.
Process aids are highly efficient additives to improve the extrusion efficiency of
thermoplastic resin by eliminating surface defects and increasing output. PPAs are used
in processes such as blown film, cast film, blow molding, wire and cable jacketing, pipe
and tube extrusion and extruded fiber processing. Significant benefits are demonstrated
at very low levels of addition to wide range of resins.
