Sponge Rubber

Sponge rubbers are closed cell rubbers which are impervious to air, water, and dust. They are most commonly used for weather stripping and gasketing applications. Sponge rubbers are formed by combining ingredients and then molding the compound under heat and pressure. During the molding process, gas is used to create the unique cellular structure of the sponge. An array of compounds, such as Neoprene, EPDM, SBR, and Vinyl Nitrile are available to meet specific needs such as resistance to heat, flame, ozone or petroleum products.

Common Applications:

Weather stripping for automotive glass applications
Gasketing for acoustical/speaker mounts
Sealing exterior lighting (headlights/tail lamps)
HVAC/Air handling system seals and thermal insulation
Vibration isolators for interior automotive components

Available Sizes:

Thickness: .1.6mm - 25mm
Width: 2mm - 1000mm
Length: 2mm - 1700M
