Chemical purging

Chemical purging is a method of purging injection molding machines of residue, colorants, and other contaminants when changing molds, materials, or colors. This method has been adopted by many molders, especially those who use molds with hot runner systems. Chemical purging compounds are 100% moldable and react with the resin and pigment to remove residue faster with less purging material used. Ultra Purge offers many grades of chemical purging compound for a variety of applications and machinery.
