Are your applications future-proof?
With the new EU Drinking Water Directive (DWD) and the REACH Regulation, lead limits for components carrying drinking and heating water will become significantly stricter from 2027 onwards. In many cases, this will effectively prevent the use of metallic materials.
For many manufacturers of water-carrying components and systems, this means one thing: existing solutions must be re-engineered.
The solution: metal replacement
The right high-temperature polymer meets the regulatory requirements while also offering decisive advantages in terms of cost, weight, functional integration and space efficiency.
Many projects fail because they attempt to replicate a metal component one-to-one in polymers.
Replacing metal with polymers is not a simple material substitution. It requires a complete redesign from an engineering perspective.
Successful solutions require:
- Polymer-appropriate joining technologies and sealing concepts
- Optimised component geometries
- Designs tailored for injection moulding
- Efficient material usage - leveraging rib structures instead of excessive wall thickness
- Deep material expertise covering chemical, mechanical, and thermal stresses
- Careful selection of materials for the specific application - because not all polymers are the same!
Metal replacement in practice
A strong example of effective metal replacement is the new heat pump hydraulic system by Viessmann (part of Carrier Global Corporation).
Working closely with the customer, we redesigned the entire concept and developed a completely new polymer solution that also meets the latest requirements of the REACH Regulation.
