DuPont™ Purge Resin

DuPont™ Purge resin is a fractional melt index low density polyethylene (LDPE) resin that contains various additives to assist in purging and cleaning extruders. This polymer is formulated with agents to help it wet and scour metal surfaces within the extrusion system. It also contains a blowing agent that helps to disrupt normal flow patterns and enhance scouring action. The resin normally will foam, snap and crackle as it leaves the die. A somewhat fishy, ammonia smell is detectable from the extrudate and feed hopper. When extruded, the resin has a grayish brown color and a very high viscosity at the die exit.
