Polytechs Clean X: High-quality cleaning compounds

Hamburg, 17 August 2017 – Polytechs’ Clean X high-standard purging compounds are a convincing product family in terms of their outstanding quality and versatility, which allow for customer-specific solutions to be developed and implemented with the support of Nordmann, Rassmann GmbH.

The Clean X product line from Polytechs is used to chemically and mechanically clean equipment for processing plastics. There are specific Clean X compounds for extrusion, injection molding and hot runner applications that help remove deposits from processing equipment without residue and thereby allow production to begin again more quickly. Even when cleaning blow molding machines, production does not have to be stopped for cleaning processes to take place.

Adjusting the viscosity and using certain specific additives provides for high-efficiency cleaning that saves on both materials and costs. Another advantage of using these cleaning granules is that they are safe for contact with food, which opens up additional fields of application.

Both temperature and polymer decide
The compounds in the Clean X line are especially effective at cleaning because they can be individually matched to specific polymers. Therefore, in addition to temperature, the type of polymer that is to be removed also plays a decisive role in selecting the most suitable Clean X compound. Depending on the type of application, the specialists from Nordmann, Rassmann GmbH can make recommendations from the following:

- Clean HDPE
- Clean HT
- Clean LDPE
- Clean PP
- Clean PS
- Purge LDPE V3

- Clean HDPE
- Clean HT
- Clean PP
- Clean PS

- Clean HD-HR
- Clean PP-HR
- Clean LLDPE-HR

The granules can be used in temperatures ranging from 100 to 260°C. Polytechs is also currently developing a high-temperature purging compound that is to allow cleaning at temperatures higher than 300°C.


Having a company laboratory at its manufacturing site in Cany-Barville, France permits Polytechs to continuously develop its own products and offer new, individualized solutions together with Nordmann, Rassmann GmbH. Specific formulations can be put directly into production at the site, which is equipped with a great deal of diverse specialist machinery and also benefits from regular investments.
