Sanitary technology

Drinking water approved seals, components and tubings

The silicone products in the various SANIBIW qualities meet the requirements of both national and international drinking water directives . They correspond, in many points, to the KTW directive of the German Federal Environmental Agency (see Table) and can be approved extensively within the framework of international regulations. BIW offers you comprehensive advice when it comes to the selection of suitable material qualities especially applicable for pure silicone rubber and/or textile reinforced drinking water tubings. In addition, many silicone products from BIW can also be found in other sanitary technology applications, used for functional purposes such as shower cubicles and installation seals as well as for decorative sealing and attaching solutions.
