AIREX® C70 is a closed-cell, cross-linked rigid foam with excellent rigidity and a great stiffness to weight ratio. It is highly durable, has a low water absorption rate and excellent chemical resistance. It can be processed with all commonly used resin systems and processes. The fine cell structure supports excellent adhesion of face sheets.

AIREX® C70 is the ideal core material for many lightweight sandwich structures subjected to dynamic or static loads.

It is non-friable, contains no CFC’s, has negligible water absorption, and provides an excellent resistance to chemicals. The fine cell structure offers an excellent bonding surface. Compatible with most resins and manufacturing processes AIREX®C70 is ideally suited as a core material for a wide variety of sandwich structures subjected to both static and dynamic loads. Thanks to its unique lightness (properties vs. density) C70 is the material of choice for applications where lightweight is a priority.

AIREX® C70 is the ideal core material for many lightweight sandwich structures subjected to dynamic or static loads.
