Abstract
An extruder system for rapid change between different melt strength polymers is provided. The extruder system includes at least three polymer extruders; a flow spool; and a multilayer feedblock including a first combining zone, a second combining zone, and at least one cartridge insert arrangement in each of the first combining zone and the second combining zone; where each cartridge insert arrangement is configured to receive a cartridge insert, the cartridge insert directing flow of a polymer from one of the polymer extruders. Also provided are method of forming an encapsulated coating with the extruder system and an encapsulate coating formed with the extruder system.
