DIAB expands Divinycell range of structural polymer cores

DIAB has further expanded its extensive range of structural polymer with three new additions. Its Divinycell H grade now includes two new densities (H35 and H160) and its Divinycell HP grade as been augmented with a one new density (HP160).

Divinycell H160 & HP160
The decision to introduce a 160 kg/m3 density to both DIAB’s Divinycell H and HP grades is particularly due to the fact that the proportion of larger boats being produced is on the increase and more and more designers and builders are requesting a density between the existing 130 and 200 kg/m3 for use in hull bottoms.

By offering the additional density, DIAB maintains that designers and builders will be able to more accurately match the density to the loads. This should result in better weight optimization and reduced core material costs.

Both H160 and HP160 offer extremely good mechanical properties, excellent adhesion and peel strength to all marine resin systems. As is the case with the other densities in the H and HP range, the 160 kg/m3 densities offer very good impact resistance and slamming behavior.

Divinycell H35
With a nominal density of 38 kg/m3, Divinycell H35 is one of the world’s lightest structural foam core.

In common with other densities in the Divinycell H range, H35 offers good strength and modulus properties, low water absorption and is resistant to attack from styrene and other solvents. It also features a small cell size to minimize resin usage and can be processed at up to 90°C with minimal dimensional changes.

Divinycell H35 sandwich core can be supplied with a wide range of finishes to facilitate installation, enhance component quality and to meet specific process requirements. In addition H35 can be supplied in ‘ready to use’ kits.

The addition of H35, further strengthens the position of Divinycell H grade as the structural core material that offers the widest range of densities (38, 45, 60, 80, 100, 130, 160, 200 and 250 kg/m3). As a result designers and specifiers are able to more closely match the density to the specification requirements of the application.
