Hot polymer filtration
Case

Consistency and quality give longer filter life

The fibres in the shirt you are wearing could have been made using a process in which Höganäs metal powders are a key component.

Höganäs is today one of the world's largest suppliers of filtration products for the textile industry. The particles of our metal powder have a large active area and an irregular shape which ensures optimum cleaning during filtration.

Our customers assemble the powder into a so-called spin pack - the media the receives the liquid polymer. As the polymer passes through the spin pack, the polymer's impurities and contaminants are removed thanks to the metal powder particles. Once filtered, the polymer is spun into fine synthetic fibers such as nylon or polyester, later used for production of synthetic textiles.
