AIREX® PXw.320

1 of 27 products in this brand
AIREX® PXw is a closed-cell, fiber reinforced polymer foam panel with a special formulation and very high mechanical properties. The sophisticated manufacturing process evenly distributes continuous glass fibers with woven fabrics throughout the foam. This generates a product with enhanced mechanical properties in flexure (bending), allowing it to be used with or without face sheets.AIREX® PXw is dimensionally stable, does not lose strength when wet, and is resistant to chemicals and high emperatures. It is ideally suited as a material for static applications requiring high stiffness or as a replacement for wood and plywood.
