ArmaSport Foam (ALC, AHC, MC)
SKU# ALC-012-25
Armacell's Armasport ALC elastomeric closed cell foams are designed for use in Aerospace, Automotive, and Marine applications. These foams have excellent resistance to oil, fuel, and water, and can be used in both indoor and outdoor applications. This foam is notable for its use as carpet padding, cushioning for seat components, or in headliners and sidewalls. It can also be used for gasketing or sealing applications.
Sold in 25-ft rolls. Rolls may have a skin layer on one side. ±1/16" tolerance on all thicknesses. ALC thicknesses over 1/2" and AHC and MC thicknesses over 1/4" will have a 15-day lead time. If any thicknesses indicate that they are sold out, please contact us for options as they may be available with a 15-day lead time.
Note: Includes FAA burn certificate for 25.853(a), except for 1/8" and 3/16" ALC, which do not pass FAR 25.853(a) vertical burn test when tested alone, but do pass when sandwiched between acceptable materials, such as in armrests, carpet padding, wall padding, etc.
