2 lb. Polyurethane Mix and Pour Foam |
| For Floatation and Sculpting |
| #24/25 is a two-part, equal mix, self-rising, 2lb/ cu. ft. density closed-cell foam system. Foaming begins within 45 seconds after the two liquids are mixed and continues for several more minutes. The foam expands approximately 30 times its liquid volume before curing, and will fill any shape cavity. It does not react with oil or gasoline and it will not absorb water. #24/25 is ideal for floatation applications and provides 60 pounds of floatation per cubic foot of foam. Unlike polyester foams, polyurethane foam is compatible with both polyester and epoxy resins.

Polyisocyanurate Foam Sheets |
| Pattern-Making and Moldless Designs |
| Our polyurethane foam sheets have the same properties as the mix and pour foam listed above, but come in rigid sheets of varying thickness. They are suitable for most sandwich core applications and are ideal for those which require insulating cores. This foam is easily cut and shaped with a sharp knife and sandpaper. Pattern-making has never been quicker! It can also be glued together to form blocks as thick as necessary for shaping functional moldless-type parts. |

End Grain Balsa |
| Standard Marine Grade Core |
| End Grain Balsa is the most widely used core material. We have it available in 2' x 4' sheets of individual small blocks of end grain balsa bonded to a light scrim fabric that holds the blocks together while laminating. Sheets of this core will conform to practically any simple curve and most gradual compound curves. 9.5# density. |

Vinyl Foam |
| Versatile, Formable, and Water Resistant |
Closed cell vinyl foam is an excellent core material with superior mechanical properties! When used as a structural sandwich core, this foam provides low weight, excellent stiffness as well as high insulation! This foam is used extensively in aircraft and automotive applications and is compatible with all of our resins. Can also be easily thermoformed with a heat gun or oven!
3 Lb. Density Sheets 32" X 48"

Nomex ® Honeycomb |
| Lightest Possible Construction |
| Parts which require minimum weight often employ Nomex® honeycomb sandwich cores. #1562 and #2562 are .210" cut thickness with a 3/16" overexpanded cell. #1562 is 1.8 lb/cu ft. density and #2562 is 3.0 lb/cu ft. Both are quite flexible due to the overexpanded cell structure, making them perfect for use in tight radius curves. All of our resins will bond well to the phenolic coated honeycomb, reducing peel.
