3A Composites Core Materials AIREX® C70.250 Universal Structural Foam

AIREX® C70 is a closed cell, crosslinked polymer foam that combines excellent stiffness and strength to weight ratios with superior toughness. It is non-friable, contains no CFC’s, has negligible water absorption, and provides an excellent resistance to chemicals. A 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 lightweight sandwich structures subjected to both static and dynamic loads.

Characteristics

• outstanding strength and stiffness to weight ratios
• Good impact strength
• Low resin absorption
• High fatigue resistance
• Good fire performance (self-extinguishing)
• Sound and thermal insulation
• Good styrene resistance
