Chemical resistance
The chemical properties of polyethylene are significantly improved by the cross-linking process.
DUOPEX WATER Pipes are resistant to the following media:
- Concrete, plaster, mortar, and cement.
- Disinfectants and cleaning agents according to DVGW worksheet W 291 and DIN 2000.

If the DUOPEX WATER pipe and fittings installation system is used in areas where, for example, aggressive gases, permanently acting moistures or building materials containing chlorine are to be encountered, the FITTINGS have to be protected using suitable jacketing. This also applies to contact with screed, concrete, mortar or plaster.
Always consult the manufacturer for details.
