Description: Style AG1366 is a medium density flame retardant closed cell silicone sponge material designed to be utilized in gasketing applications that require a soft compressible material. Style AG1366 is UV and ozone resistant and takes a low compression set. Medium density flame retardant closed cell silicone sponge offers resistance to low and high temperatures and provides users with an operating temperature of -103°F to +450°F. A flame retardant and highly compressible material, medium density flame retardant closed cell silicone sponge is formulated to meet the physical requirements of MIL-R-6130 Type 2 Grade A Medium, and is capable of meeting the UL 94 HB and DMS1980 specifications.
Atlantic Gasket’s closed cell silicone sponge gasketing material is available in a wide range of densities from soft (AG1346-S) to extra-firm (AG1346-XF) with varying densities and formulations available in between. Medium density flame retardant closed cell silicone sponge can be converted into rolls ranging from 1/4" wide up to 36" in width. Dark blue in color, the surface of Style AG1366 has a fine fabric finish on both sides and can be manufactured in rolls or sheets with a thicknesses range from as thin as 1/32", to as thick as 1/2". Atlantic Gasket has the ability to supply medium density flame retardant closed cell silicone sponge without adhesive or choose from either our standard acrylic adhesive or our high-temperature acrylic adhesive. Send in a drawing, and let Atlantic Gasket die-cut or waterjet cut medium density flame retardant closed cell silicone sponge to meet your prototype and production requirements.
