Rigid foam core materials Sandwich applications with AIREX® foams are up to 50% lighter than conventional solutions require less energy while preserving highest strength, stiffness, and thermal insulation. Significant weight reduction due to AIREX® foams allows switching mass from dead weight to payload. Due to its lower weight-to-stiffness ratio, AIREX® foams influence continuous improvement in renewable energy sector allowing construction of longer turbines. Below grades represent standard dimensions. 3A Composites has a wide portfolio of core materials, for more information on all available grades and dimensions please contact IMCD.
