3/8" thick, approx 4.5lb density, grid scored and perforated urethane foam core.
Excellent core for infusion or wet layup. Acts as a flow media to distribute resin to both sides, so doesn’t need additional flow media over it. Very strong and light, and makes super strong and stiff panels even just using fiberglass.
The sheets are about 48"x48" and were purchased for testing purposes. Before it discolors from sitting in my office, I thought some of you may be interested since it’s nearly impossible to acquire without buying by the case or pallet.
Price is only $49 per sheet or $90 for 2. If you want more, let me know and we’ll work something out to clear up space!
