3D|CORE™ makes light foams strong.
This mechanism is easy to understand. The resin structure has higher technical properties (e-modulus) than the surrounding foam. Through this the resistance against the deformation, either by shear or by compression forces, is much higher than foam.
The foam and the resin build a hybrid core. The improved technical properties create a very nice performance to weight ratio.
For XPS - foam the increase in shear and compression strength can be up to 250% higher than basic XPS - foam. The shear modulus can be improved up to 500 % about the basic foam. This means that it is possible to reach the level of a 130 kg/m³ SAN - foam.
This gives you the opportunity to use low cost foams instead of high end foams.
