have you used this? Should I get #2 or #4 density? Thanks.
To be clear, Jig you meant the 4# foam will support more weight like standing on it while on the deck its supporting, not that as flotation foam its support (float) more weight then the 2lb, correct?
[SIZE=+1]2 LB [/SIZE]Density Urethane Foam
(U.S. Coast Guard Compliant Marine Foam)[SIZE=-2]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 this product strictly for flotation applications.[/SIZE]
[SIZE=-2]Product Information:
Free Rise Density: 2.0 lbs per cubic ft.
Expansion Rate: Approx. 25-30x Liquid Volume
Buoyancy (flotation): 60 LBs per Cubic Ft.[/SIZE]
[SIZE=-2]*Physical Properties:
Parallel Compressive Strength: 40 psi
Tensile Strength: 30 psi
Shear Strength: 30 psi
Flexural Strength: 50 psi[/SIZE]
[SIZE=+1]4 LB[/SIZE] Density Urethane Foam [SIZE=-2]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. [/SIZE]
[SIZE=-2]Product Information:
Free Rise Density: 4.0 lbs per cubic ft.
Expansion Rate: Approx. 15x Liquid Volume
Buoyancy (flotation): 58 LBs per Cubic Ft.[/SIZE]
[SIZE=-2]*Physical Properties:
Parallel Compressive Strength: 90 psi
Tensile Strength: 110 psi
Shear Strength: 70 psi
Flexural Strength: 120 psi[/SIZE]
