The Cloeren developed SelectorPlug™ is an interchangeable cartridge located upstream of the combining section. It enables the operator to quickly change the layer structure without completely disassembling the Feedblock. By simply exchanging the SelectorPlug with one having a different channel routing, you can alter the product layer sequence in less than 30 minutes.

The patented TopHat™ design, like the Selector Plug Cartridge, provides an easy means for altering layer structure sequencing. It allows rapid overhead change without disassembly of the Feedblock or melt delivery piping. Available for use in numerous applications, the TopHat is best suited for applications comprising a large number of extruders, and for low viscosity applications.
