TPEs for Drinking Water Applications
When our water supply goes on its journey to our taps, we don’t want its quality to be impaired by unwanted odours, colours or flavours. We also want to help safeguard against any microbial contamination along the way.
We have developed Dryflex DW, a special range of Thermoplastic Elastomers (TPE) especially for applications that come into contact, either directly or indirectly, with drinking water. This can include both domestic and commercial applications such as plumbing seals, pipe fittings and shower-heads. Dryflex DW TPEs have passed the German drinking water regulations KTW as well as W270 approval.
Certifications
In developing the Dryflex DW TPE compounds, we carefully selected the raw materials to ensure they are compliant with food contact and water hygiene standards.
Dryflex DW TPE compounds have been tested and approved according to ‘The Guideline for hygienic Assessment of Organic Materials in Contact with Drinking Water’ (KTW Guideline)
The Dryflex DW TPE compounds have also been approved according to DVGW Technical Standard W270 which describes a test method to determine the microbial growth on non-metallic materials intended for use in drinking water systems.
