AIREX® C70 - universal structural PVC foam

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 common 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 subject to dynamic or static loads.
