Key Cost Points ecomate® has resulted in reduced foam

density as low as 22,4 kg/m3 Free Rise Density.

Commercial experience shows ecomate requires less molar equivalents than HC’s.

ecomate requires less flame retardant to achieve rated foam than HC’s.

ecomate is a small part of overall demand for the molecule and there are multiple plants in the world.
