Fiber-reinforced structural foam
AIREX® PXc is a closed-cell, fiber-reinforced urethane foam with special formulation that offers significant advantages in comparison to conventional sandwich core materials. A special manufacturing process is used to distribute continuous fiberglass filaments evenly in the PXc foam. This creates a very smooth product with excellent compressive and shearing properties. The foam is dimensionally stable, shows low water absorption and is resistant to chemicals and high temperatures. AIREX® PXc is an ideal core material for sandwich elements subjected to high stress loads or as a substitute for wood and plywood.
Fiber-reinforced sheet of structural foam
AIREX® PXw is a closed-cell, fiber-reinforced urethane foam with special formulation that offers significant advantages in comparison to conventional sandwich core materials. A special manufacturing process is used to evenly distribute continuous fiberglass filaments with mesh in the foam. This creates a product with increased bending resistance and rigidity, which enables utilization with and without face sheets. The foam is dimensionally stable, maintains stiffness even when subjected to moisture and is resistant to chemicals and high temperatures. AIREX® PXw is an ideal core material for static applications requiring a high level of rigidity or as a substitute for wood and plywood.
