Typical Properties of Medium Density Flame Retardant Closed Cell Silicone Sponge

Description: Medium density flame retardant closed cell silicone sponge material designed to be utilized in gasket applications that require a soft compressible material. This material 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.

M&P Sealing’s closed cell silicone sponge gasket material is available in a wide range of densities from soft to extra-firm 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 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″.M&P Sealing 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 M&P Sealing die-cut or waterjet cut medium density flame retardant closed cell silicone sponge to meet your prototype and production requirements.
