Typical Properties of Style AG1346-XF Extra-firm Density Closed Cell Silicone Sponge

Description: Style AG1346-XF is an extra-firm density closed cell silicone sponge material designed for use in gasketing applications that require an extra-firm compressible material. Extra-firm d density closed cell silicone sponge offers resistance to low and high temperatures and provides users with a service temperature of -103°F to +450°F. Style AG1346-XF is UV and ozone resistant and takes a low compression set. Extra-firm density closed cell silicone sponge is formulated to meet the physical requirements of ASTM D1056, and MIL-STD 670.

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. Extra-firm density closed cell silicone sponge can be converted into rolls ranging from 1/4" wide up to 36" in width. Available, in many colors, the surface of Style AG1346-XF has a fine fabric finish on both sides and can be manufactured in thicknesses ranging from as thin as 1/32", to as thick as 2". Atlantic Gasket has the ability to supply extra-firm density closed cell silicone sponge without adhesive or with either our standard acrylic adhesive or our high-temperature acrylic adhesive. Atlantic Gasket has the capacity to fabricate extra-firm density closed cell silicone sponge by die-cutting or waterjet cutting to meet your requirements from the design stage through the production phase.
