[Case Study] Color Change in Molding Foamed PP Using Hot Runner Molds

The resin cleaning agent [Selpurge] makes it very easy to clean hot runners, which has traditionally been difficult. It improves the efficiency of the color change process during molding.

"Serpaj" is a cleaning agent for injection molding machines and extruders that excels in color change for hot runners and removal of black spots. It can shorten setup times and reduce resin discharge volume and material loss.
