Ekoprodur S0541

Closed-cell system

System description

EKOPRODUR S0541 is a two-component system for the production of closed-cell, self-extinguishing, rigid polyurethane foam. The foam’s excellent insulating properties have been achieved through the use of HFO – a fourth-generation foaming agent from the group of hydro-fluoroolefins with a low greenhouse effect potential GWP = 1 and zero ozone-depleting potential ODP = 0. The system is mainly used for external insulation and sealing of flat roofs.
