AIREX® C71

Temperature-resistant structural foam

AIREX® C71 is a closed-cell, cross-linked rigid foam with high temperature resistance, 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® C71 is the ideal core material for lightweight sandwich structures for dynamic or static loads subjected to increased temperatures.
