PURPOSE:To provide a cleaning agent for molding machine having excellent cleaning effect for extruder and injection molding machine. CONSTITUTION:A resin composition for cleaning is made of a heat resistant styrene resin 100 pts.wt. having a Vicat softening point of 115 deg.C or above at a load 1.0 kg., a polyalkylene oxide glycol 0.5-100 pts.wt. having viscosity- average molecular weight 10,000-1,500,000, 8-20C alkyl sulfate and/or metallic salt 0.5-10 pts.wt. of 6-22C fatty acid. This cleaning agent is useful for extruder and injection molding machine. The cleaning agent can clean not only general purpose resin but also modified PPO and resin having high heat deforming temperature in a short time with a small quantity of material. Besides, replacement by following material can be done very easily. |
