Celanese Corporation, the global technology and specialty materials company, showed a closed water circulation system that demonstrated the benefits of engineered materials used in filtration, storage and distribution.

Ensuring the supply of water is one of the main tasks of the future. Thus, water and materials in contact with water are already subject to the most stringent regulations. Proven materials for drinking and waste water systems include: Hostaform acetal copolymer (POM), Fotron polyphenylene sulfide (PPS) and GUR ultra-high molecular weight polyethylene (UHMW-PE). Celanese offers more than 30 years of experience and supports customers in processing with specialist consulting – through to the finished product.

Hostaform POM
Components can be coded with drinking water colors, slip-modified or fiber-reinforced, which make this material ideal for numerous water applications, from sprinklers through housing components to adapters for hoses.

Fortron PPS
It is ideal for use in water system applications, especially as a cost-saving substitute for metals. Glass fiber-reinforced grades provide great design freedom and allow for the integration of different functions in various components. Fortron PPS is approved contact with drinking water, and is used fittings, water meters and recirculation pumps, and hot water boilers.

This material is used in filtration — either compact as semi-finished products, injection molded parts or sintered for specific porosity. The most important properties of the material are the abrasion and wear resistance that ensure reliable function over a long period. Porosity and geometry of the porous part can be tailored to suit specific application requirements, making it an ideal material for filters with or without activated carbon.
