At NEDC, we manufacture custom gaskets all day. One material we use to cut custom gaskets is polyurethane foam. Polyurethane foam is very popular for gap filling, gasketing, and shock absorbing applications. ISOLOSS™ is made by a 3M subsidiary E-A-R.
Properties of ISOLOSS LS Foams by E-A-R AEARO
ISOLOSS™ Polyurethane Foam is made up of fine, small cells. The material is versatile. It features a low compression set, and offers low outgassing. All of the tested data is highlighted in the brochure downloadable below. Some other features of the material include:
-High energy absorption
-Effective Vibration Isolation
-Great chemical resistance
-Flame Resistance, certified to UL HBF at certain thicknesses across materials
-A broad temperature range (40°F to 225°F)
-High internal strength (ISOLOSS™ features higher tear, and tensile that competitive brands)
-With the exception of LS-10xxLM*, all of the ISOLOSS™ materials are certified to UL-50, UL-508, and UL-514B.
What is ISOLOSS utilized for?
ISOLOSS is designed to be a gasketing material that can support the following functions:
-Sealing in NEMA graded boxes
-Mitigating Buzzing, Squeaking, and Rattling is dynamic applications
-Gap Filling for shock
-Sealing/Gasketing in minimum intrusion applications.
Below is a list of materials:
LS-10xxLM* (10lb density) – LS-15xx (15 lb density)- LS-20xx (20 lb density) – LS25xx (25 lb density)

NEDC utilizes waterjet-cutting, die-cutting and other methods to cut these materials into finished shapes. ISOLOSS™ comes in 4.5’ wide rolls, and has a 5 year shelf life. In addition, if you need adhesive backing on ISOLOSS™, NEDC can provide this material with a 3M acrylic backing such as 3M 9472 or 9485PC adhesive tape. The typical color is a plain black.
