Open Cell Sponge Natural Rubber

Since 1947, Atlantic Gasket Corporation has been supplying die-cut parts, gaskets, tapes, and other products to original equipment manufacturers (OEMs) based across the United States and around the world. Among our selection of available materials is open cell sponge natural rubber. The compression set resistance of open cell sponge natural rubber makes this material an ideal choice in many industrial and commercial applications. Read on to learn some of the many applications where our natural rubber open cell sponge can be used.

Materials Properties Applications
Natural Rubber Open Cell Sponge Expansion joints, gap fillers, cushioning, vibration absorption, and non-skid padding Natural rubber open cell sponge is available in five densities: RO11 (soft), RO12 (medium), RO13 (medium firm), RO14 (firm), and RO15 (extra firm). This material is supplied with a textured finish on both sides. Standard roll width is 36", but can be made up to 54" wide for 1/16" up to 9/16" thick and up to 48" wide for 5/8" up to 1" thick.
Die Ejection Material Used as die ejection packing in steel rule, rotary and Class A dies Die ejection natural rubber is available in three grades: style 3261 (28 pcf. density), style 3271 (32 pcf. density), and style 3281 (36 pcf. density). Standard sheet sizes include 12” w. x 18” l., 18” w. x 36” l., and 36” x 36” square. For additional information, see open cell sponge rubber sheeting die ejection.
Extruded to a Round Profile Drum gaskets and applications where the material is sewn in (Example: A strap on a handbag) This natural rubber product is available in two densities – high or low. Our natural rubber compound is used for applications involving temperatures up to 158˚F. It can also be made from EPDM, which has a high temperature rating of 210˚F and will hold up well in applications that will be sealing dilute acids. Standard sizes include 3/8", 13/32", 7/16", and ½" diameter. See our industrial open cell sponge cord for more specifications.
