Listed according to: KTW/W270, ACS, NSF 61 and WRAS
AKRO-PLASTIC, a compounder situated in Niederzissen, Rhineland-Palatinate, now offers technical plastics for drinking water contact, listed according to KTW/W270, ASC, NSF 61 and WRAS. Furthermore, the raw materials comply with EU 10/2011 and FDA that makes them suitable for the use in food contact.
The demand for clean and accessible drinking water is an important component of humanity. Therefore, strict regulations and standards apply to the materials that come into contact with drinking water. The increasing use of plastic requires special materials that comply with the legally regulated drinking water regulations.
In the European Union, these drinking water regulations are regulated nationally, the most important regulations include: In Germany KTW (Plastics in Drinking Water Contact) and DVGW (German Association of Gas and Water Supply eV), in France ACS (Attestation de conformité sanitaire) and in Great Britain WRAS (Water Regulations Advisory Scheme).
In the US, the standard NSF 61 (Drinking Water System Components - Health Effects) regulates plastic contact with drinking water.
These regulations specify low migration levels, low odor and taste levels, and low microbial growth.
For the previously listed drinking water listings, we are pleased to provide you with the appropriate test certificates and thus facilitate the approval of your plastic components.
Discover the Benefits of Plastics vs. Metals
In contrast to the most commonly used brass components, plastic offers greater design freedom, which means that it is possible to integrate multiple components and significantly increase their functionality. The density advantage can reduce costs of additional proccessing steps.
The used metals increase the proportion of heavy metals in drinking water. Furthermore, the plastic components are significantly lighter due to the lower density of the plastic compared to the metal.
Another advantage is the significant reduction of metal ions in the water.
AKROMID® T5 is based on a partially critical thermoplastic polyphthalamide (PPA) with a glass transition temperature of approx. 130 °C. The product family includes unreinforced compounds reinforced with up to 50% glass fibers. It can be used for moulded parts which are exposed to higher temperatures. Moreover with PPA compounds, the influence of moisture absorption is very low, so that it is very well suited for mechanically stressed components in drinking water and food applications.
The replacement of metals by engineering plastics in the drinking water and food sectors has risen steadily. A wide variety of applications are already made of plastics, such as fittings, water meter housings, filter housings and seals.
