Ekoprodur S0331FL

Closed-cell system

System description

EKOPRODUR S0331FL 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, thanks to the use of, HFO – a fourth generation foaming agent from the group of hydro-fluoroolefins with low greenhouse effect potential GWP = 1 and zero ozone depletion potential ODP = 0. It has been designed for internal insulation of floor surfaces. It is characterised by increased mechanical resistance and very good dimensional stability.
