High gas barrier of cell membrane, for prevention of gas release and long-term retention of high-performance insulating effect.

Difference from initial value at ambient 20°C, in W/mK

Elapsed time (months)

The NEOMA™ Foam cell membrane, with its high gas barrier, retains the foaming gas and blocks air entry. In foams without a high gas barrier, the outside air gradually replaces the foaming gas and thus lowers insulation performance.
