Polymer Removal

Remove Polymer from Spinnerets, Dies & Extruder Screws

Polymer Removal

Kolene® molten salt cleaning processes remove polymer deposits from spinnerets, pack bodies, extruder screws, dies, and related production components.

When a workload is first immersed into the cleaning bath, the molten salt “freezes” on the cooler metal surface and slowly remelts as it heats up the metal.  Treatment times vary from a few seconds to several minutes, depending on the polymer and load.

Kolene No. 10 and No. 10W salts remove polymers such as:

  • polyesters
  • polyamides (nylon)
  • polypropylene
  • polyvinyl chloride (PVC)
  • polystyrene

We can provide a basic cleaning system consisting of the cleaning unit and water rinse tanks sized for your production requirements.  We can also provide a complete processing line, starting with a melt-out oven to remove solidified polymers from pack bodies and other tooling.  We can also supply multiple rinse tanks, ultrasonic final cleaning stations, brighteners, and air blow-off and drying stations.

Have parts like these? Tell us the alloy, the coating or residue, and your volume, and we will recommend the salt and equipment for the job.
