Cores in sandwich construction are specified by designers and architects to increase stiffness and reduce the weight of a composite structure. Corecell™ is the leading structural foam core material, which has become widely accepted for the construction of large, high performance structures. It is the latest in foam core technology and although originally developed for the marine industry, it is now used in other applications such as wind turbines and sub sea vessels.

Corecell™ uses SAN polymer base, resulting in unique high toughness and impact resistance characteristics. The foam acts as a 'shock absorber' between the two skins - absorbing the impact without failing, distributing the stresses evenly within the core and, in the case of a boat, ensures it remains watertight even after high point impacts.

Corecell™ foams provide low weight, excellent stiffness, and structural integrity under dynamic loads. They have high shear elongation and retain their mechanical properties even in the higher ambient temperature range. The insulation values are constant over time due to controlled, CFC-free foaming process.

Corecell™ foams are compatible with polyester, vinylester, and epoxy resins. However, we recommend appropriate tests are carried out to check the bond/compatibility with any resin system used. Epoxy resins bond well to the Corecell™ foam, but through a mechanical bond; as there is no chemical interaction the integrity of both the epoxy and the core is maintained.

Corecell™ is type approved by the American Bureau of Shipping (ABS), Lloyds Register of Shipping, Det Norske Veritas (DNV) and Germanischer Lloyd (GL).
