AIREX®C70
Product Details
DESCRIPTION
AIREX® C70 is a closed cell, cross-linked 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. 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.
CHARACTERISTICS:
Outstanding strength and stiffness to weight ratios
Good impact strength
Low resin absorption
High fatigue resistance
Good fire performance (self-extinguishing)
High sound and thermal insulation
Good styrene resistance
