Influence of Compatibility

Compatibility is a key factor for no residue of purging compounds in the subsequent moldings.

It is especially important for hot runner systems, be careful to choose the appropriate grade.
In addition to the compatibility, surfactants also play a key role. The surfactants in CELPURGE, which controls interfacial tensions when CELPURGE discharges the molten plastics, gathers between metal surface and CELPURGE when CELPURGE itself should be discharged and replaced to the subsequent plastics, then they work as a lubricant. Thanks to them, CELPURGE slide on the surface of screw/barrel. Thus CELPURGE can be discharged very smoothly.
