AGSIMEDIUM is a medium density closed cell silicone sponge which is designed for gasket applications requiring a low compression set and has a resistance to extreme temperatures. The medium density silicone sponge has a closed cell structure which prevents water absorption of less than 3% per ASTM D1056 and has a smooth surface finish allowing for better sealing and the ability to apply an adhesive. AGSIMEDIUM is formulated per AMS3195, ASTM D6576 Type II, ASTM D1056, MIL-R-46089, MIL-R-6130 Type II, FDA, UL94 V-0, and UL94 HB. Atlantic Gasket’s AGSIMEDIUM silicone sponge endures a temperature range of -103°F (-75°C) to 500°F (260°C) intermittent and also has excellent resistance to oxidation, UV, ozone, and weathering.
AGSIMEDIUM medium density silicone sponge, offered by Atlantic Gasket, comes in a variety of widths, thicknesses, and colors (red, white, grey, and black). This silicone sponge is also available in soft density (AGSISOFT), firm density (AGSIFIRM), and flame retardant option (AGSIFIRES, AGSIFIREM, and AGSIFIREF) along with widths of up to 36" and thicknesses from .062" to 1". AGSIMEDIUM has the ability to have a pressure sensitive adhesive laminated to this silicone sponge, and Atlantic Gasket can slit it to widths as narrow as ¼" or as wide as 36". The silicone sponge can be cut to size for custom parts either using our high-speed die-cutting process or our high-precision waterjet-cutting machine for production quantities and/or prototype requirements.
