Title: PROCESSES FOR CLEANING MELT PROCESSING EQUIPMENT
Abstract:
A process for cleaning melt processing equipment used to compound, mold and/or extrude a polymeric resin includes supplying to the melt processing equipment a particulate purge material comprising polyethylene having a viscosity number from 300 to 3,500 ml/g and an average particle size, d50, from 50 to 1000 micron, heating the melt processing equipment to a temperature sufficient to allow the purge material to be extruded through the equipment, and running the equipment to extrude the purge material while cleaning the melt processing equipment.
