Common Applications: Our 2LB density marine foam is recommended for void filling in nonstructural applications. This product can be poured underneath decks and inside cavities where a lightweight flotation foam is needed to provide buoyancy. This foam has been tested in accordance with U.S. Coast Guard Regulation # 33 CFR 183.114 . This foam is approximately 95-98% closed cell which resists absorbing water, however continuous water submersion can eventually lead to loss of buoyancy over a period of years.

** We recommend the 2LB FOAM strictly for flotation applications. If looking for a liquid foam for sculpting or casting we recommend using at minimum our 3LB or 4LB density.**

Flexural Strength: 50 psi

Common Applications: Can be used as a lightweight foam for carving or sculpting as well as some limited casting applications Gives better detail than our 2LB density foam. The 4LB density should be used for better quality castings and improved strength. More questions? [Try our Foam FAQ.]

Product Information:
Free Rise Density: 3.0 lbs per cubic ft.
Expansion Rate: Approx. 20x Liquid Volume
Buoyancy (flotation): 59 LBs per Cubic Ft.

*Physical Properties:
Parallel Compressive Strength: 60 psi
Tensile Strength: 70 psi
Shear Strength: 50 psi
Flexural Strength: 70 psi

Common Applications: This 4LB density foam is suited well for most flotation applications that require more support than the 2LB offers. This foam is recommended to be used when supporting gas tanks and some deck areas. Choose this density if you feel that the foam will be required to withstand minor to moderate loads. The 4LB density also works well in floating decoy or taxidermy applications as well as many other sculpting, casting, carving and other filling applications. More questions? [Try our Foam FAQ.]
