Kunststoffe international, 2005-11-21, Filter Cups Made from Polyamide: Transparency for Water Filters
Engineering Plastics Transparency for Water Filters Filter Cups Made from Polyamide. Modern filter systems would be inconceivable without plastics. The transparent filter cups in water filters made by Carbonit Filtertechnik are produced from Grilamid, a thermoplastic polyamide 12 that absorbs virtually no water and is approved for food and drinking-water contact applications. Peter Westerbarkey Engineering plastics play a key role in professional filter systems. They allow the greatest possible...
