Application:
Divinycell® H has a proven track record in virtually every application area where sandwich composites are employed, including the marine (leisure, military and commercial), land transportation, wind energy, civil engineering/infrastructure and general industrial markets.
Processing:
Continuous operating temperature is typically -200 ºC to +70 ºC. The foam can be used in sandwich structures, for outdoor exposure, with external skin temperatures up to +85 ºC.
Maximum processing temperature is dependent on time, pressure and process conditions.
