In mid November Divinycell HM was launched at METS Marine Show in Amsterdam.
It is available in three densities 80, 100 and 130 kg/m³.
“Divinycell HM is a high performance structural core designed for fast marine hulls where higher toughness is required. Divinycell HM combines a very high shear strength with an outstanding shear elongation. As a result, Divinycell HM is an extremely tough product, capable of absorbing high dynamic impacts and slamming loads.
Divinycell HM´s elongation exceeds the requirements of ISO 12215, GL and ABS rules to allow for reduced safety factors in structural calculations, providing a lighter, yet strong structure.
Divinycell HM’s high compressive properties provide excellent resistance to denting and skin wrinkling of thin skins.
Divinycell HM offers a high operating temperature, thus reducing the risk of prints on dark hulls.”
If you compare the data sheet with Divinycell H you will notice that the big difference is in the 80 kg material only, which now has a higher shear elongation to get the design rebate mentioned in the quote above.
Material will be available in February-March 2015.
