A cleaning composition for a molding machine and a cleaning method. |
摘要 |
<p>Disclosed is a cleaning composition for use in cleaning the interior of a molding machine having residual molding resin retained therein, comprising (a) a specific graft polymer comprised of a main chain comprising an olefin polymer and having, grafted thereto, a side chain comprising a styrene polymer and (b) a thermoplastic styrene polymer, the graft polymer (a) and the thermoplastic styrene polymer (b) being present in a weight ratio of from 2/100 to 160/100. This cleaning composition exhibits an extremely excellent cleaning effect due to its high capability to scape off a residual resin on a metallic surface. By using this cleaning composition, the cleaning of the interior of a molding machine having a residual molding resin retained therein can be effectively and efficiently performed in a short period of time and at a low cost.</p> |
