Cleaning compound for film extrusion |
|---|
|
Quality demands for extruded films are getting more and more severe. Customers require Just-In-Time supplies, resulting in ever shorter production runs with more frequent changes in colour. ECONOCLEAN cleaning compound offers an efficient and economical solution for single- as well as multilayer films. |
| Singlelayer film: | Regular maintenance with ECONOCLEAN prevents burnt residues to stick to the screw, the cylinder wall and in the dies. This will prevent the formation of black specks, and accelerates changes of material and/or colour. |
| Multilayer film: | ECONOCLEAN will, apart from the above mentioned properties, also very effectively remove the (usually very adhesive) innerlayers and barrier materials (EVA, PE, resp. EVOH, PA). It will clean all extruders and the die at the same time. |
| The result: | A very effective, preventive cleaning system, which reduces efficiently and rapidly scrap and the loss of time when changing colours or material. |
| Less downtime | ECONOCLEAN works effective, and reduces the need for pulling the screw. |
| Shorter start-up time | ECONOCLEAN removes black specks effectively, making the start-up phase for the next run shorter, causing |
| Reduced loss of material | through shorter start-up periods, and |
| Less cleaning compound | ECONOCLEAN needs only 1½ to 2 times the cylinder contents for an effective cleaning. |
| Concentrated | ECONOCLEAN is available in ready-for-use formulations, but also as a concentrate. |
| Less scrap |

 | ECONOCLEAN | is a resin that is as easily processable as plastics. |
| ECONOCLEAN | is composed of materials that have the GRAS classification (FDA norm for Generally Recognized As Safe). |
|---|---|---|
| ECONOCLEAN | is odourless, also when processed. No special precautions are required. |
| The residue is a plastic with inert minerals, which can be processed as such. | ||
| ECONOCLEAN | is available in 25 kg quantities, in recyclable carton boxes with a plastic liner. |
Process | TOP |
| Econoclean will foam slightly in the extruder, so it reaches into the dead corners of the extruder and die. Burnt residues are released from screw and cylinder wall through a chemical reaction, and extruded by the purging properties of Econoclean. Econoclean also has a polishing (NOT abrasive) effect, which leaves the surfaces inside the extruder clean and smooth. |
 Regular preventive maintenance controls the building up of burnt residues, and makes every cleaning more effective. |
