Airex PXc Board, from Baltek, is high density, glass-reinforced urethane foam panel. Applications include rotted plywood transom replacement in outboard motor installations. Formerly known as Penske and similar to Coosa Board, Airex PXC can be used as a foam or balsa core replacement when thru-bolting deck hardware, plywood replacement for small-boat cockpit soles, under-deck autopilot installations etc.
With the addition of fiberglass mat or fabric on either side, this product will have very good screw-holding ability. Absolute minimal water absorption. Not designed for cosmetic applications, typically used with fiberglass skins added to both sides. Easily cut with standard woodworking tools.
These PXc.385 boards are all 24lb density.
