Divinycell H Grade can be used for the vast majority of composite applications where both hand laminating and closed moulding processes such as infusion are employed. With the upgraded H Grade, major improvements have been made in all critical performance areas. Strength properties have risen by up to 15%. In addition elongation to break has risen dramatically by up to 65% and the ductility has also been markedly improved.

Both the thermal and dimensional stability have also seen significant improvements. Divinycell H can now be processed at up to 90°C (+194°F) with minimal dimensional changes. The chemical resistance has also been enhanced. Another major improvement is a reduction in the core’s cell size. Divinycell H is available in a very wide range of densities as standard sheets or fabricated to customers specification as kits.

Technical Data for Divinycell H Grade

Continuous operating temperature is -200°C to +70°C (-325°F to +160°F).The foam can be used in sandwich structures, for outdoor exposure, with external skin temperatures up to +85°C (+185°F). Operating conditions must be taken into consideration for the very low and high temperatures. Maximum processing temperature is dependent on time, pressure and process conditions. Normally Divinycell H can be processed at up to +90°C (+194°F) with minor dimensional changes. Please contact DIAB for advice before use. Coefficient of linear expansion: approx. 22.2 x 10-6/°F (40 x 10-6/°C)
