HYPOX was developed by Italy-based MOVEngineering for removal of polymers adhering to various mechanical parts. Nearly 400 units have been sold around the world. Safe and easy to operate, the cleaning system applies hydrolysis, pyrolysis, and resin oxidation to remove solidified polymers stuck on nozzles, filters, gear pumps, extruder screws, and molds used in film or fiber production as well as substances such as carbon residuals, oligomers, and gels that are difficult to remove conventionally. No solvents or chemical substances are used in this automated, unattended process, which does not damage products. Not only is the system effective in removing oligomers and gels, it’s especially useful in cleaning delicate parts such as sintered metal filters, which are not damaged in the process. Capable of relatively low-temperature cleaning, HYPOX does not weaken common heat-sensitive metal base materials or surface finishes.

① Hydrolysis: Anaerobic removal of polymers, gels, and oligomers with steam at about 400 °C
② Oxidation: Removal of carbon residuals with heated air at over 400 °C

These two processes are combined to remove polymers stuck on parts in an automated sequence that normally takes 8–15 hours.

Proven to be effective for PET, PA6, PA66, PC, PP, PE, PBT, PU, ABS, COP, COC, cellulose, and other polymers
*Can be tested for cleaning of other polymers

A testing facility is being established in Iwakuni, Yamaguchi.
