Abstract
A composition comprising 10-80% by weight of a cellulose ether and a solvent selected from a water-soluble polyhydric alcohol, polyhydric alcohol ether, polyhydric alcohol ester, and ethanolamine is effective for purging extrusion and injection molding machines. The purging composition exerts a satisfactory purging or cleaning effect, but little abrasion effect, thus avoiding any abrasion of machine internal components by purging. Even if part of the purging composition is left within the machine after the composition is discharged out, the residue can be readily removed.
