Overview
| Rigid, Polyether Polyurethane foam with fine closed-cell structure, light cream-yellow color. LAST-A-FOAMŪ is wonderfully versatile for sandwich-core applications. It cuts and shapes easily with common woodworking tools, and bonds to itself and other materials with most epoxy, polyester, or urethane-type adhesives. LAST-A-FOAMŪ is unaffected by water, fuels and most solvents, and paint finishes are easily applied. It is frequently used in regular molds after the gel-coat and first two layers of glass are installed; the LAST-A-FOAMŪ is added and another layer of glass applied for a strong, light-weight sandwich. |

This is a fragile material to begin with and I ordered the 1/4 thick version. So first..it was available, thanks . Second...the packaging was terrific with a heave honey combed cardboard to protect it.
There are only a few suppliers of 1/4 Last-A-Foam and here is a great source to get it from. Great packaging protected it and delivery was quick.
The foam was as expected. An Aircraft Spruce was close enough so I was able to use will call and avoid the special shipping charges with over sized packages.
Item was perfectly packaged for shipping and item arrived in great condition.
Foam material was what we needed to complete our task.
Great material to work with. Easy to shape and hard as rock when covered with fiberglass and epoxy. I used that in strips for the gunwale of my mini tugboat and it worked great even with the compound curve of the gunwale. The shipping was truly impressive. There was no way the foam could get damaged unless it was run over by a truck. It arrived in perfect condition. This was my second order of this same material and both shipments were perfect.
This foam seems to work the same as the old Clark foam which is no longer available. I was very impressed with the packing when it arrived in perfect condition via UPS.The box was made of several layers of heavy cardboard with three 4-foot-long wooden stiffeners taped inside. The foam inside was wrapped in brown paper to keep it clean. Nice job, ACS!

No. Last-A-Foam is a polyurethane base foam and should not be hot wired.
Yes. Last-A-Foam is a urethane base foam, and will not be damaged by vinylester resin.
As long as its not a laser machine. If it's a die cut or water then yes.
This foam is used for many in mold, and sandwich construction applications. It's not intended to be heat formed, so we have no info how well heat forming would work. Depending on the application, a micro-slurry is sometime used before laying up fiberglass or other reinforcement.
Yes, this is FR-3706.
Yes, but it is not returnable once cut.
Part # 01-13500 is FR3704.5
Yes, Last-A-Foam is a polyurethane base foam so you can use viinyl-ester resin without any damage to the foam.
This is fairly stiff material. It is hard to rate how bendable it is because it will bend in the full sheet form, but will not bend around 90* corners.
FR-3708 corresponds to 01-01048.
